Schottenheimer retained by Ryan

New York Jets offensive coordinator Brian Schottenheimer, once considered a candidate to replace deposed head coach Eric Mangini, will remain in the role under Rex Ryan, team sources told ESPN senior NFL analyst Chris Mortensen.

Schottenheimer is one of several Jets assistants retained by Ryan, who signed a four-year deal and was introduced by the team on Monday. Offensive line coach Bill Callahan and special-teams coordinator Mike Westhoff also will be back.

Ryan hired Ravens outside linebackers coach Mike Pettine as his defensive coordinator.

Both Callahan and Schottenheimer were beaten out for the job by Ryan in a lengthy interview process by the Jets. Ryan is formerly the defensive coordinator of the Baltimore Ravens.

The Jets' biggest offseason issue on offense is whether Brett Favre will return. The 39-year-old quarterback is mulling retirement again after tearing a biceps muscle and throwing nine interceptions in the Jets' last five games -- the Jets lost four of them after an 8-3 start and missed the playoffs.
