I'm not going to claim to be football smart, but I have watched the first 2 weeks' QB School videos and that is almost as good as staying at a Holiday Inn Express last night.
I came away from Sunday's game thinking that the poor QB performance was mostly on Fields and that he apparently was just never going to be the guy. Sure there has been bad playcalling and a bad supporting cast, but a true franchise QB should be able to overcome some of that.
After watching that QB School video last night, I think the actual answer may be even worse. It appears the Bears have taken what started as a guy with a few flaws, haven't fixed those, and have simultaneously made his strengths worse. O'Sullivan pointing out plays where it looks like Fields has regressed in his ability to simply throw the ball was eye-opening. That raises the possibility that maybe the underlying problem is less on Fields himself. Maybe he could have been a good QB if he went somewhere else, but the Bears infrastructure is where QB prospects go to die. Has the lack of an adequate offensive line and WR targets (up until this season) completely broken or prevented the development of whatever internal clock and/or decision-making process that Fields needs to have in his head? Could any QB have developed successfully in this situation?
