Mangini, who began his NFL career as a ballboy for the Browns, was introduced as Cleveland's 12th full-time coach on Thursday, less than two weeks after he was fired by the New York Jets.
The 37-year-old Mangini signed a four-year deal with the Browns, who are rebuilding once again following a 4-12 season that ended with the firings of coach Romeo Crennel and general manager Phil Savage.
Browns owner Randy Lerner hasn't decided on a GM yet, but the frontrunner is George Kokinis, Baltimore's director of player personnel and a longtime friend of Mangini's.
Mangini went 23-25 with one playoff loss in three seasons with the Jets, who started 8-3 this season but lost four of their last five games and missed the playoffs.
