High school career

McKnight attended John Curtis Christian High School in River Ridge, Louisiana, located approximately 10 miles west of New Orleans in Jefferson Parish.

For his first years of high school, McKnight played defense as a cornerback; his high school career was complicated by the aftermath of Hurricane Katrina, which devastated his part of Louisiana just before his junior 2005 season. Separated from his mother who had evacuated to Baton Rouge, McKnight temporarily relocated to Shreveport where he eventually enrolled and played two games for Evangel Christian Academy, the same school which previously produced USC quarterback and future teammate John David Booty. His family was able to relocate back to River Ridge, but their home had been destroyed so they moved into a one-bedroom apartment.

For the rest of the shortened 2005 season, McKnight scored 22 touchdowns (nine rushing, five receiving, four punt returns, three interceptions, one kickoff return) and averaged 18 yards a play in leading his team to the state championship. In 2006, McKnight rushed for 719 yards on 45 carries, scoring 14 touchdowns, had 24 catches for 735 yards and 13 touchdowns, and with special teams play scored a total of 30 touchdowns as a senior; he was instrumental in John Curtis Christian's 14-0 season, often used as a decoy player due to his scoring threat.

McKnight is the latest and arguably the most talented of a line of running back prospects out of John Curtis Christian HS-among them Reggie Dupard, Chris Howard and Jonathan Wells. Most recruiting analysts rank him among the top 2 of the 2007 high school class (next to quarterback Jimmy Clausen of Oaks Christian High School). Considered a 5-star recruit, on January 28, 2007, McKnight was named co-Player of the Year by Parade, sharing the honor with Clausen. Rivals.com ranked McKnight the best running back prospect in the U.S., and the 2nd best recruit overall. Analysts notice his elusiveness and impressive speed (10.59 seconds in the 100 meters and 4.3 seconds in the 40-yard dash), as well as his incomparable instincts and field vision but some say he is somewhat undersized, at 205 pounds (93 kg), for the college game. McKnight has been called “the most exciting prospect the state of Louisiana has produced since Marshall Faulk” by recruiting analyst Jamie Newberg.

USC assigned linebackers coach and former NFL All-Pro Ken Norton Jr. to handle recruitment of McKnight. LSU coach Les Miles visited McKnight on February 1, 2007, the last possible date before National Signing Day, in order to ensure McKnight's commitment to the LSU. However, on February 7 McKnight committed to the University of Southern California. At USC, McKnight was joined by second-ranked running back prospect, Marc Tyler. The backlash against McKnight's decision to attend college out of state manifested itself when the Curtis School's marching band was booed performing at a Mardi Gras parade.

McKnight stated that his interest in USC came from its football tradition, notably Heisman trophies and his interest in sports broadcasting, noting the USC Annenberg School for Communication.

Recruiting controversy

McKnight told reporters on National Signing Day that he spoke to former USC running back Reggie Bush before he chose Southern California over favored LSU. On February 9, the Los Angeles Times reported that USC officials were investigating whether an NCAA recruiting violation occurred during the Trojans' pursuit of the Louisiana prep star. At issue is whether McKnight listened to a phone call between head coach Pete Carroll and Reggie Bush. NCAA rules state that alumni cannot speak to players and attempt to persuade them to join their former school.

Joe McKnight and his high school coach, J.T. Curtis, would both later claim that McKnight misspoke during the news conference and that McKnight has never actually met or spoken to Bush. Bush and Carroll denied that a conference call ever took place. Carroll blamed the controversy surrounding McKnight on LSU fans who were unhappy that McKnight would choose to leave the state of Louisiana and attend USC.

College career

Because of his talent and versatility, the media and opposing coaches have called McKnight the "next Reggie Bush". McKnight began college at the University of Southern California in June 2007. He was awarded with the inaugural “Frank Gifford Endowed Football Scholarship”, which is given out annually by the USC athletic department to an incoming freshman running back, quarterback or wide receiver who best emulates Gifford's life, success and spirit. By the pre-season practice before his freshman season at USC, McKnight had already demonstrated some of the speed and moves that made him an impact player in high school.

After a slow start during his freshman season, dealing with fumble-issues for the first time in his career, he made a pivotal contribution in a victory against Arizona, where he ran a punt return for 45 yards, and later ran for 59 yards to set USC up for their last 10 points in their game.

McKnight achieved a break-through at the end of his freshman season during the 2008 Rose Bowl, where he had 206 all-purpose yards: 36 on three punt returns, 45 on six pass receptions and 125 in 10 carries with one touchdown.

During his freshman season, McKnight painted "I need $" under his eye blacks to signify his desire to play professional football in the NFL.

Before his sophomore season, McKnight was included in Sports Illustrated's spring list of top ten Heisman Trophy contenders going into the fall. However, his sophomore season was hampered early on by medical conditions, fumbles and injuries, including a nagging metatarsalphalangeal joint sprain that prevented him from playing in two games. In February 2009, Bobby Burton of Rivals.com summed up his career by writing, "McKnight really hasn't lived up to the hype. He's good, but he just hasn't broken out to show he's the best back in his class".

In his final college football season it was reported that McKnight was granted free use of a 2006 Land Rover SUV registered to Santa Monica businessman Scott Schenter, in violation of NCAA rules. Schenter responded, claiming that the SUV actually belonged to McKnight's girlfriend, Johana Michelle Beltran, although McKnight has reportedly been seen driving it around town. As a result of the pending investigation, the USC compliance department would not clear McKnight to play in the 2009 Emerald Bowl.

On January 8, 2010, McKnight declared his intention to forgo his final year of eligibility, hired an agent and entered the 2010 NFL Draft.

New York Jets

2010

McKnight was drafted by the New York Jets in the fourth round (112th overall) of the 2010 NFL Draft. To select McKnight, the Jets traded up twelve spots in the fourth round with the Carolina Panthers. In return, the Jets sent their fourth (124th overall) and sixth (198th overall) round selections to Carolina. McKnight formally signed with the Jets on June 22, 2010.

McKnight struggled in the early stages of his professional career, vomiting during the Jets' rookie minicamp in May 2010. McKnight later admitted he had not been in proper condition at the time. He continued to struggle into the preseason, fumbling the football three times. Though he was not in danger of being released from the team, it was maintained that McKnight would not appear on the active roster until the coaches felt more confident in his abilities. McKnight made his NFL debut on October 3, 2010 against the Buffalo Bills and was used in a limited capacity on offense before being utilized as an emergency cornerback and on special teams over the course of the season. In McKnight's first game as the starting running back, against the Bills during the Jets' final regular season contest, McKnight ran for 158 yards on 32 carries with no fumbles and caught two passes for 15 yards.

2011

During the Jets' 2011 home opener against the Dallas Cowboys on September 11, 2011, McKnight blocked Matt McBriar's punt on a critical play resulting in a touchdown by fellow defender Isaiah Trufant. The Jets went on to defeat the Cowboys 27-24. During the Jets' Sunday night game against the Baltimore Ravens, on October 2, 2011, McKnight returned a kickoff for 107 yards, his first career touchdown. It was the longest play in Jets history. On January 16, 2012 Mcknight was named as the Kick Returner for All-Pro team By Pro Football Weekly / Pro Football Writers Association.

2012

On September 26, 2012, Jets head coach Rex Ryan announced that McKnight would see an increase in defensive snaps at cornerback. The announcement was prompted after Darrelle Revis suffered a season-ending ACL tear. Shortly after the announcement was made, McKnight was switched back to his former role as a running back. On October 8, 2012, McKnight returned a 100-yard kickoff for a touchdown against the Houston Texans, recording his second career touchdown. Elias Sports Bureau reported that McKnight had extended the Jets' NFL record of most consecutive years with a kickoff return for a touchdown to 11 years.

He was released by the Jets on August 26, 2013.

Kansas City Chiefs

After spending the entire 2013 year out of football, McKnight signed with the Kansas City Chiefs on January 12, 2014. On July 21, McKnight was placed on the Physically Unable to Perform list. On September 21, 2014, in a game against the Miami Dolphins, he scored two times on receptions from Alex Smith. McKnight suffered a torn Achilles' tendon during practice on September 26, 2014 and was ruled out for the rest of the 2014 season.
