Playing career

High school

Mangini was a linebacker at Bulkeley High School in Hartford, Connecticut.

College

Mangini played nose tackle at Division III Wesleyan University and holds the school's single-season (11.5) and career (36.5) sacks records. During the second semester of his junior and senior years, he coached the Kew Colts, a semi-professional football team in Melbourne, Australia, to two regional championships. Mangini joined the Chi Psi Fraternity that coaching mentor Bill Belichick, a Wesleyan alumnus, was part of two decades earlier.

Coaching career

NFL

Assistant coach

Mangini first caught the attention of Bill Belichick, under whom he would coach for nine seasons, as a 23-year-old ball boy with the Cleveland Browns. His work ethic impressed Belichick, and the head coach was instrumental in promoting Mangini to a public relations intern, and later, an offensive assistant.

After spending 1996 as an offensive assistant with the Baltimore Ravens, Mangini rejoined Belichick and spent three seasons as a defensive assistant with the New York Jets. When Belichick was hired as the New England Patriots head coach in 2000, he brought along Mangini as his defensive backs coach. Mangini, who won three Super Bowls with the Patriots, turned down defensive coordinator positions with the Miami Dolphins, Oakland Raiders and Cleveland Browns before accepting the role with New England in 2005.

Head coach

New York Jets

Mangini, 35, became the youngest head coach in the NFL when he was hired by the Jets on January 17, 2006, to replace Herm Edwards. He beat internal candidates Donnie Henderson, Mike Heimerdinger and Mike Westhoff and external candidates Jim Haslett, Mike Tice, Tim Lewis and Joe Vitt for the job. He was quickly nicknamed "The Penguin" by receiver Laveranues Coles because of his waddle and fierce stare.

In his first season, Mangini led the Jets to a 10-6 record and a postseason berth with NFL Comeback Player of the Year quarterback Chad Pennington. New York, which finished the previous year 4-12, lost to New England in a wild-card playoff game.

New York went 4-12 in 2007, failing to make the playoffs. Early in the regular season, Mangini complained to league officials that Belichick's Patriots illegally filmed the Jets' defensive signals, exposing the "Spygate" scandal.

In 2008, a late-season collapse—the Jets missed the playoffs despite an 8-3 start—led to Mangini's firing on December 29, 2008, one day after the season ended.

Cleveland Browns

Mangini was hired as the head coach of the Cleveland Browns on January 7, 2009, signing a four-year deal. Mangini faced early criticism in his tenure with Cleveland for his tendency to micromanage the team and his disregard for the team's history (one of his first acts was to tear down a mural of Browns greats on the wall of the team office). Sports Illustrated columnist Joe Posnanski went so far as to call Mangini's hiring by the Browns as the worst coaching hire from the past 25 years. In his 2013 memoir, former player Nate Jackson, who was briefly part of the Browns practice squad during the 2009 preseason, sharply criticized Mangini. Jackson wrote that Mangini's coaching style had so alienated his players that they seemed "deep in despair" with "no fight left in them" only a few months after Mangini took over.

After starting his first season in Cleveland 1-11, the Browns bounced back with a win over their division rival and defending Super Bowl champion Pittsburgh Steelers. This started a four-game winning streak to end the season with a 5-11 record. On January 7, 2010 it was announced that Mike Holmgren had decided to retain Mangini as head coach of the Browns for the 2010 season.

Mangini's second season was highlighted with back-to-back upsets over the defending Super Bowl champion New Orleans Saints and New England Patriots. The Browns had been forced to start rookie quarterback Colt McCoy due to injuries to starting quarterback Jake Delhomme. The season also saw the breakout of running back Peyton Hillis. These developments however did not amount to any marked improvement, as the Browns once again finished 5-11.

On January 3, 2011 Mangini was fired with a 10-22 record as the head coach of the Browns.

San Francisco 49ers

Mangini was hired by the 49ers as a senior offensive consultant on June 4, 2013. On February 20, 2014, he was promoted to be the tight ends coach. On January 22, 2015, he was again promoted to be the defensive coordinator. However, after just one season, he was released along with most of the coaching staff after Jim Tomsula was fired.
