An interesting what if about the Nussmeiers
I think Philly offers him the OC job.
That would seem like the best scenerio, he has some talented players to coach, good chance to get back to Super Bowl and good chance for head coaching job in the future.
However, something to consider, his boy is playing his final college season right down the road. (great chance to see him during the week or maybe catch a game)
Coaching offense for his former team might play a factor.
He might be real good buddies with Moore and want to help him succeed.
He might welcome the challenge of taking on a hard job as offensive coordinator for the Saints
He also may not like Philadelphia (weather, he social environment)
