Pro Career:Mangini was introduced as coach of the Browns on January 8, 2009.
Mangini previously served as coach of the New York Jets 2006-08. Mangini went 23-25 and made the playoffs once in three seasons with the Jets, who stumbled down the stretch to lose four of their last five games and miss the playoffs after an 8-3 start.
He joined the Jets following six seasons with the New England Patriots (2000-05), the first five of which he served as the defensive backs coach before earning a promotion to the defensive coordinator's position.
In his first five seasons with the Patriots, he tutored a secondary that earned five Pro Bowl selections and evolved into one of the NFL's most successful defensive backfields despite suffering numerous injuries.
Prior to joining the Patriots, Mangini served as an assistant on Bill Parcells' coaching staff with the Jets (1997-1999), where he worked primarily as the defensive assistant/quality control coach. During that time, he worked closely with Bill Belichick, who was the Jets' assistant head coach/secondary coach. Mangini was also responsible for advance opponent film breakdowns and analysis.
In 1999, the Jets' defense ranked third in the AFC with 24 interceptions, the team's highest total since 1969 (29). In 1998, the Jets' defense surrendered just 16.6 points per game, helping the Jets to a 12-4 overall record and their first division title, while advancing to the AFC Championship game.
In 1996, he served as a quality control/offensive assistant on Ted Marchibroda's coaching staff with the Baltimore Ravens. Mangini's first NFL coaching opportunity came in 1995 as an assistant on Belichick's Cleveland Browns staff. While completing his Wesleyan degree in Melbourne, Australia, Mangini served as the head coach and defensive coordinator for the Kew Colts, a semi-professional football team, and led them to back-to-back titles.
