As I think mentioned before he was getting permission to be interviewed for the Colts job. I imagine though with the Eagles just winning the Super Bowl that certainly makes his resume stand out even more.
Somewhere I read he gets overlooked a lot because he's too nice a guy. I think after Marrone left he got interviewed for the position here. When Rex got hired being the class act he is he still had good things to say about Ryan and how he was the right fit.
He got a Super Bowl ring, but would be nice to see a solid guy like that get a HC position instead of say the Rex Ryan's of the world. Of course that's if he wants it
