I dont' think ICE understands that Ego is everything with a QB. You get young hotshot QB's out of college who have been the **** since Highschool. They come into the NFL usually on crappy teams with crappy Olines and get destroyed. Joey Harrington, and David Carr come to mind. they both got hammered every sunday lost all confidence in themself and their organizations.
Guys like Cutler, Rodgers, Brady, etc... spent at least a year or so on the bench. they weren't thrown into the mix and got to watch.
