Mangini became the youngest coach in the NFL when the former Patriots assistant took over the Jets in 2006. In his first season with the Jets, he led them to a 10-6 record and a playoff berth after the team finished 4-12 the previous year. The Jets missed the playoffs the next two seasons and he was fired.
Mangini was named the Browns' coach in January 2009. After two consecutive 5-11 seasons, Mike Holmgren replaced him.
Mangini worked as an ESPN guest analyst during the 2010 NFL playoffs.
