In regards top the EJ stuff, being an older guy I remember the days when a QB was drafted to sit behind the veteran and learn, it worked much better than the "win now, start now" that has invaded the NFL in the last 2 decades. I think EJ sitting behind a veteran for the year could really pay off. I don't think he will ever be Manning or Brady, but he has the tools to maybe be like a Wilson. Natural athletic ability isn't everything, but it is a big help. Maybe his mind works a quarter second slower than the top guys and learning how to prepare, recognize, and operate could overcome that. I don't know for sure not being in the building. His accuracy,which was suspect coming out of FSU, is my biggest concern and don't know if it can be fixed.
As far as Marrone I have seen many posts on here about him, I have see every coach make foolish game time decisions, Marrone is no different any other coach, even the great Belicheck (sp?) does it going for 4th down against Indy at his own 20).
Hacket I don't know if it the play calling or the execution.
