Early years

Cassel was born in Northridge, Los Angeles, California. When Cassel was 11 years old, his family home was at the epicenter of the 1994 Northridge earthquake, which at one point trapped his father Greg under a marble column and caused water from their swimming pool to flood their house. Their home was eventually condemned as a result, forcing the Cassel family to move.

Cassel was the starting first baseman on the Northridge baseball team that reached the finals of the 1994 Little League World Series.

Cassel attended Chatsworth High School and was a letterman, an all-city selection, and a standout in both football and baseball. As a senior, he was ranked as the number eight quarterback and number 53 overall of the top high school players in the nation according to ESPN's Tom Lemming's Top 100. Lemming called Cassel a "pro-style pocket passer with a very strong, accurate delivery." In addition to playing quarterback, Cassel was also Chatsworth's punter.

Cassel committed to play at USC before starting his senior year in high school.

Cassel also had an appearance in the HBO Family program Freshman Year, a reality show in which his younger brother was one of the featured students.

College career

Cassel began his college career in 2001 and spent that entire Trojan career as a backup behind Heisman Trophy winners Carson Palmer and Matt Leinart. Cassel was the backup for Palmer during his Heisman-winning 2002 season. In the fall, Cassel lost the battle for the starting position to the previous third-string quarterback in Leinart. As a result of Leinart's success, Cassel spent time at tight end and wide receiver in 2003, and some special teams that year. He made his lone collegiate start at H-back against California in 2001. During his four seasons at USC, Cassel completed 20 of 33 passes for 192 yards, with no touchdowns and one interception.

Cassel, a communication major at USC, was also roommates with Pittsburgh Steelers safety Troy Polamalu, now retired, and Carson Palmer.

Cassel played one season of baseball for USC in 2004, compiling an 0-1 record with 10 strikeouts and 4 walks. He played in 8 games and started 1. Cassel struck out in his only at bat in college. He also had 2 saves with a 9.35 ERA, and was selected by the Oakland Athletics in the 36th round of the 2004 MLB Draft.

New England Patriots

Despite having had little chance to demonstrate his skills in actual game situations at USC, Cassel earned himself a place on several NFL teams' draft boards after working out at USC's 2005 Pro Day. One of Cassel's coaches, Norm Chow, who had left USC to become the offensive coordinator for the Tennessee Titans, had discussed signing Cassel as an undrafted free agent after the 2005 NFL Draft; Chow was surprised to learn the Patriots had drafted Cassel in the seventh round, with the 230th overall pick, ahead of more accomplished college quarterbacks such as Timmy Chang and 2003 Heisman trophy winner Jason White.

2005 season

Cassel began the 2005 season third on the Patriots' depth chart behind Tom Brady and Doug Flutie, after beating out two more veteran quarterbacks, Chris Redman and Rohan Davey. He saw his first regular season action in the closing minutes of the Patriots' 41-17 loss to the San Diego Chargers on October 2, 2005, going 2-for-4 for 15 yards and throwing an interception.

In the Patriots' final game of the 2005 regular season, a 28-26 loss to the Miami Dolphins on January 1, 2006, Cassel played the final three quarters. Though he was sacked for a safety, he threw two touchdown passes, one to Tim Dwight, and the second to Benjamin Watson. The pass to Dwight set up a drop-kick by Doug Flutie, the first such kick since 1941.

2006 season

Following Flutie's retirement in the 2006 offseason, Cassel moved up to second on the Patriots' depth chart. Although the Patriots considered signing a veteran quarterback to compete with him, Cassel played well in preseason and became the primary backup to Brady. Cassel was on the 45-man active roster for all 16 games in 2006; when the Patriots brought in yet another Heisman winner, Vinny Testaverde, Testaverde acted as the emergency quarterback.

In Week 16 of the 2006 season, after injuries to Josh Miller and Ken Walter, Cassel assumed duties as holder for kicker Stephen Gostkowski. He also led a late touchdown drive in Week 17 against the Tennessee Titans.

2007 season

In Week 7 of the 2007 season, Cassel's second pass was intercepted by Jason Taylor of the Miami Dolphins and returned for a touchdown. The next week, with the Patriots leading the Washington Redskins 45-0, he capped off the 52-7 blowout with a 15-yard touchdown run in which he dove over two Washington defenders to reach the end zone.

2008 season

In the 2008 season opener against the Kansas City Chiefs, Cassel came under center when Brady suffered a torn ACL and MCL in the first quarter from a hit by Chiefs safety Bernard Pollard. Cassel led the Patriots to a 17-10 victory, completing 13 of 18 passes for 152 yards and one touchdown; Cassel's drives accounted for all of New England's points.

The day after the game, the Patriots confirmed that Brady's serious injuries would sideline him for the rest of the season. Although the Patriots did bring quarterbacks Chris Simms and Tim Rattay to Foxborough, they signed neither, and kept Cassel as the starter.

Cassel made his first-ever start on Sunday, September 14, 2008, with a winning effort over the New York Jets, completing 16 of 23 passes for 165 yards; though he threw no touchdowns, he also threw no interceptions. The Patriots' 19-10 victory was the first time in six tries that a quarterback making his first NFL start defeated a team led by Brett Favre.

Cassel was voted AFC Offensive Player of the Week for his Week 7 performance against the Denver Broncos on Monday Night Football. He had 183 passing yards and three touchdowns in a 41-7 rout, which made it his first three touchdown pass game.

Cassel scored the second rushing touchdown of his career on a 13-yard touchdown in Week 10 against the Buffalo Bills. Cassel had zero touchdowns, but also zero interceptions, as he led the Patriots to a 20-10 win; the Patriots held the ball in the game for over 37 minutes; the final 19-play drive, which lasted over 9 minutes, tied a franchise record for most plays in a single drive.

In the Patriots' 34-31 overtime loss to the New York Jets, on November 13, 2008, Cassel led the Patriots on three consecutive scoring drives to bring them back from a 24-6 deficit with two minutes left in the first half, and threw a 16-yard touchdown to Randy Moss on 4th-and-1 with one second remaining to send the game into overtime. He finished 30-for-51 passing, with 400 yards, 3 touchdowns (and a pass for a two-point conversion), and no interceptions for a passer rating of 103.4, and 62 yards rushing on eight attempts. Cassel became the first Patriot to throw for 300 yards and rush for 50 yards in the same game, and the first player since at least the AFL-NFL merger to have 400 passing yards and 60 rushing yards in the same game.

In Week 12, Cassel led the Patriots to a 48-28 win over the Miami Dolphins, who in Week 3 had ended the Patriots' NFL record 21-game regular season win streak. While Cassel threw for just 131 yards in the Week 3 loss, his Week 12 performance topped his performance against the Jets: Cassel completed 30 of 43 passes for 415 yards, three touchdowns to Randy Moss, and one interception, for a passer rating of 114.0; Cassel also had 14 yards on two rushes, including an 8-yard touchdown run. The performance made Cassel the first quarterback in franchise history, and only the fifth quarterback in NFL history, to have consecutive games with 400+ yards passing. His efforts earned him the title of AFC Offensive Player of the Week for the second time.

In Week 15, against the Oakland Raiders, Cassel, playing just six days after the death of his father, set a new personal best, throwing for four touchdowns in the Patriots' 49-26 rout.

In Week 16, against the playoff-bound Arizona Cardinals, Cassel led the Patriots to a 47-7 blowout win through snow, sleet, and rain in the Patriots' last regular-season home game of 2008. Cassel, playing in snow for the first time ever, nevertheless completed 20 of 36 passes for 345 yards, three touchdowns, and no interceptions, while helping the Patriots remain in the hunt for the AFC East title. In a role reversal, Matt Leinart entered the game as the Cardinals' backup quarterback when Kurt Warner was pulled from the game with the Cardinals trailing 44-0; Leinart completed 6 of 14 passes, for 138 yards, one touchdown, and one interception.

In Week 17, Cassel led the Patriots to their fourth consecutive win, 13-0 over the Buffalo Bills in a game marked by winds so severe that they bent the goalposts both before and during the game. Cassel completed 6 passes out of just 8 attempts, the second-lowest attempt total in franchise history (the lowest being the 5 attempts of the 1982 Snowplow Game). Cassel finished with 78 yards, zero touchdowns, and zero interceptions; his most notable play, however, was a quick kick punt on third down in the fourth quarter; with the wind at his back, Cassel's kick landed inside the 20, and then rolled towards the Bills' end zone before it was downed, stranding the Bills at their own 2-yard line, struggling against the wind, down two scores with five minutes remaining.

Cassel, in the last year of his four-year rookie contract, was scheduled to be an unrestricted free agent in 2009. Given the quality of his performance, and the uncertainty over Brady's recovery, NFL analysts and reporters raised the question of whether the Patriots should, or would, franchise Cassel, less than three months after some of those same reporters predicted Cassel would be cut from the team.

On January 4, 2009, ESPN's Chris Mortensen reported that the Patriots would franchise Cassel. The Patriots made it official on February 5, 2009, the first day of the 2009 franchise period, and Cassel agreed to the tender two days later.

Kansas City Chiefs

2009 season

On February 28, 2009, the Patriots traded both Cassel and OLB Mike Vrabel to the Kansas City Chiefs for the No. 34 overall selection in the 2009 NFL Draft. NFL Network's Adam Schefter (now with ESPN) described as "one of the wilder and more complex behind-the-scene dramas the NFL has seen in any recent offseason," with the Tampa Bay Buccaneers proposing a three-way trade with the Denver Broncos, in which the Buccaneers would have received Broncos quarterback Jay Cutler, the Broncos would have received Cassel, and New England would have received a first-round draft pick.

Cassel then briefly became teammates with Bernard Pollard, the player whose hit in 2008 caused Brady's injury and subsequently made Cassel the starter that season. In an interview, Cassel said he would "thank" Pollard for the opportunity, but also stated that he believed the hit on Brady was "unintentional" and he never wishes to see anyone get hurt while playing.

Cassel was expected to compete with Tyler Thigpen, who started 11 games for the Chiefs in 2008, for the starting quarterback position. Since Cassel's number 16 from New England is retired in Kansas City in honor of Len Dawson, Cassel decided to wear number 7; he chose 7 because it equals one plus six. Eventually, Thigpen was traded to the Miami Dolphins.

On July 14, 2009, the Chiefs signed Cassel to a six-year, $62.7 million contract that includes $28 million in guaranteed money, and $40.5 million in total compensation in the first three seasons.

On August 29, 2009, Cassel suffered an MCL injury during the 1st quarter of a preseason game against the Seattle Seahawks. Cassel was dragged to the ground and grabbed for his knee immediately upon impact. He attempted to continue playing but called a timeout and limped off the field. Brodie Croyle started the final game of the preseason against the St. Louis Rams as well as the regular season opening game against the Baltimore Ravens when Cassel was still unable to play. Cassel, though, started every game thereafter, going 4-11. Matt Cassel threw for 2,924 yards with 16 touchdowns and 16 interceptions and had a quarterback rating of 69.9 in his first season with the Chiefs.

2010 season

In 2010 Cassel had a resurgent season starting with a 21-14 victory over the San Diego Chargers in the opening week's Monday Night Football late game at home in Arrowhead. Cassel would build off of this start helping guide the Chiefs to a 7-4 record over the first 12 weeks of football. Due to his form during November, he was named AFC Offensive Player of the Month for November. Cassel completed 90 of 144 passes (62.5%) for 1,111 yards and an NFL-leading 12 touchdowns, with just one interception. He had a 111.2 quarterback rating for the month. As a result of his performance against the Seattle Seahawks, Cassel won the FedEx Air & Ground NFL Players of the Week award, as voted by the fans.

On December 8, 2010, Cassel underwent an emergency appendectomy. It was unclear at the time whether he would be able to play in that week's game against the San Diego Chargers. The Chiefs ended up starting backup Brodie Croyle and lost the game 31-0. Cassel would return the next two games however and would lead the Chiefs to landslide wins over both the St. Louis Rams in the Governors Cup and then at home against the Tennessee Titans. The 34-14 win over the Titans, along with a loss by the Chargers to the Bengals, helped the Chiefs clinch the division title. This would be the first Chiefs playoff game in four years and the first home playoff game since 2003, the last time the Chiefs won the AFC West division. In a home playoff 30-7 loss against the Baltimore Ravens, Cassel went 9 of 18 for 70 yards passing, zero touchdown passes, and three interceptions.

In January 2011 Cassel was named as an alternate to the Pro Bowl in place of an injured Tom Brady. Cassel threw for two touchdowns and two interceptions in the Pro Bowl.

2011 season

In 2011, Cassel had led the Chiefs to a 4-4 record. During the first two games, Cassel only threw one touchdown. Those first two games were blowout losses. In the second game, Cassel threw three interceptions. Cassel finally had his first good game, throwing two touchdowns in a 17-20 loss against the Chargers. He led the Chiefs to their first win against the Vikings, where he threw for 260 yards and one touchdown. The next week, he led the Chiefs to a comeback victory against the Colts. The Colts jumped to a 17-0 lead, but Cassel threw four touchdowns and 257 yards with no interceptions to lead the Chiefs to a 28-24 win. After the game, Cassel had a 138.9 quarterback rating. In week 8, Cassel threw one touchdown though throwing two interceptions. Cassel injured his hand in a week 10 game vs. the Denver Broncos. He was replaced by Tyler Palko, and had surgery on the injured hand on November 14. On November 21, he was placed on injured reserve, ending his season.

2012 season

In Week 1 of the 2012 season, Cassel had a tremendous first half against the Atlanta Falcons, but threw two interceptions in the second half. His final stats were two interceptions, one touchdown, one rushing touchdown, and a 72.5 quarterback rating. The final score resulted in a Chiefs loss, 24-40. The Chiefs had to rely on a 91-yard run by Jamaal Charles, a safety, and four field goals to gain their first win against the New Orleans Saints, as even with excellent field position throughout the second half, Cassel could not lead the team to the endzone; he threw one interception and no touchdowns. The final score of that game was a 24-27 overtime win for the Chiefs. The next week, Cassel struggled and threw two touchdowns, but three interceptions in a 20-37 Chiefs loss against the Chargers. After the game Cassel's starting job appeared to be in jeopardy, but coach Romeo Crennel said Cassel would start the next game against the Ravens. On October 7, 2012 against the Baltimore Ravens, Cassel left the game with a head injury. Earlier in the day, a group called Save Our Chiefs rallied fans together and flew a banner over Arrowhead calling for the General Manager Scott Pioli to be fired and for Cassel to be benched. On October 11, 2012 Chiefs head coach Romeo Crennel announced Cassel had been ruled out of the October 14, 2012 game against the Tampa Bay Buccaneers and named Brady Quinn the starter for the game. At the time of Cassel's injury, he had accumulated nine interceptions and five fumbles through the first five games of the season. This mark was more than any other team in the NFL, except the Philadelphia Eagles, who also had fourteen turnovers in their first five games of the 2012 season. On October 22, 2012, Crennel named Quinn as the starting quarterback for the Chiefs following their bye week. Cassel was deemed healthy enough to play, but still given the backup role.

On March 13, 2013, sources close to the Chiefs reported they intended to trade or release Cassel. On March 14, 2013, the Chiefs released Cassel.

Minnesota Vikings

2013 season

On the same day he was released from the Chiefs, Cassel signed with the Minnesota Vikings. On September 27, it was announced that Cassel would get his first start as a Viking in Week 4 vs the Pittsburgh Steelers, due to a rib injury to starting quarterback Christian Ponder. The Vikings won the game 34-27. Due to another injury to Christian Ponder, Cassel received his third start of the season week 14 against the Baltimore Ravens. Despite a two touchdown, zero interception performance, the Vikings lost to the Ravens 29-26 during a heavy snow game. He would remain the starting quarterback the rest of the season where the Vikings finished at 5-10-1 and Cassel either played the whole game or came in to rally the Vikings from behind in all five victories.

2014 season

On March 7, 2014, it was reported that Cassel had signed a new two-year deal for $10 million. It was later announced on August 25, 2014 that Cassel would be the starting quarterback over rookie Teddy Bridgewater and Ponder. However, on September 21, 2014 Cassel broke his foot against the New Orleans Saints and was placed on injured reserve.

Buffalo Bills

2015 season

On March 10, 2015, the Vikings traded Cassel along with a sixth round 2015 NFL Draft pick to the Buffalo Bills in exchange for a 2015 fifth round pick and seventh round pick in 2016. Cassel was involved in a three-way quarterback competition between former Bills first round pick EJ Manuel and former Baltimore Ravens backup Tyrod Taylor. After losing the competition to Taylor, he was released by the Bills on September 5, 2015. However, he was re-signed three days later to back up Taylor. Cassel was credited as the Bills' starting quarterback for the season opener due to him taking the team's first snap on offense in the wildcat formation with Tyrod Taylor lined up at wide receiver.

Dallas Cowboys

2015 season

On September 22, 2015, the Bills traded Cassel to the Dallas Cowboys after Tony Romo suffered a broken collarbone. In addition to Cassel, the Cowboys also received Buffalo's 2017 seventh round pick in exchange for Dallas' 2017 fifth round pick.

Although Brandon Weeden was expected to start, the Cowboys covered themselves by also trading for Cassel. After Weeden lost the 3 games he started, Cassel replaced him as the starting quarterback while the injured Romo continued to rehab. He was never able to have any sustained offensive success and was prone to critical errors. On December 19, after a disastrous showing against the New York Jets, Cassel was benched and replaced by Kellen Moore for the game and the rest of the season. In his seven starts and eight appearances, he posted a 1-6 losing record, 1,276 passing yards, 5 touchdowns and 7 interceptions.

On Cassel's last play before being benched for Moore, he became the first quarterback in over twelve years to throw an interception that was also flagged for intentional grounding. The play was designed to be a WR bubble screen, but Cassel held onto the ball after a pump-fake, then turned to look at the other side of the field. Forced to scramble to get away from the immediate pressure, thanks largely to most of the Dallas offensive linemen moving to the left side of the field to block for the presumed WR screen, Cassel stumbled and nearly fell over. Trying to salvage the play, Cassel threw the ball towards the right sideline. No Dallas receiver was in the area, and the ball failed to reach the sideline and was intercepted by Darrelle Revis. On top of the intentional grounding call against Cassel, there was also an illegal lineman downfield call against Dallas, as several offensive linemen had run downfield to block for what they assumed was a quick screen pass to a receiver. Both penalties were declined so that the interception would stand.

Tennessee Titans

2016 season

Cassel signed with the Tennessee Titans on March 10, 2016.

Personal life

Cassel married his longtime girlfriend Lauren Killian, a former USC volleyball player, in February 2007; Carson Palmer was his best man.

Cassel has three siblings: older brother Jack (who is married to Killian's USC roommate and teammate, Julie Mariani), younger brother Justin, and younger sister Amanda. Jack pitched for the Houston Astros in 2008 and signed in January 2009 with the Cleveland Indians. Justin is a pitcher for the Charlotte Knights, a AAA baseball affiliate of the Chicago White Sox.

Cassel is the son of Emmy-winning set decorator Barbara Cassel and her husband Greg Cassel; they divorced when Cassel was 14. Cassel's father died on December 8, 2008.

On the night of January 26, 2012, a fire broke out in a family's house in the village of Loch Lloyd, Missouri. Cassel, seeing smoke from the fire, ran to their house to alert them. The family was able to make it out of the fire alive.
