Jets block Callahan from Titans O.C. job

Is there trouble in paradise?

For the second time since the season ended in Pittsburgh, the Jets have blocked an assistant coach from interviewing for a better position with another team. This time it's Bill Callahan, the offensive line/assistant head coach. New Titans coach Mike Munchak wanted to speak with Callahan about their offensive-coordinator vacancy, but permission was denied by the Jets, ESPN's John Clayton reports.

The Jets were within their rights to block the move because Callahan is under contract for 2011 and, by rule, teams don't have to grant permission unless it's for a head-coaching job. The same thing happened recently with secondary coach Dennis Thurman, who was blocked from interviewing for the Raiders' defensive-coordinator job.

Rex Ryan thinks the world of Callahan and doesn't want to lose him, but it's a delicate situation because Callahan would like to be a coordinator. That, of course, would help his chances of becoming a head coach again. Right now, he's stuck behind Brian Schottenheimer. If the Jets fired Schottenheimer, the heir apparent would be Callahan, but Ryan and GM Mike Tannenbaum said after the season that Schottenheimer is coming back.

Ryan made it sound like a slam-dunk decision, but from what we hear, it wasn't nearly that easy. What saved Schottenheimer? Probably his contract, about $1 million per year.

Sources say that assistant OL coach Mike Devlin also received interest from other teams to be a line coach, but he, too, was denied permission.
