Honestly, I think it goes back to the fact that he only played one year in college and was not exposed to situations that a multi year starter would have been, like he should have been. Then he gets to the pros and since he was that high a draft pick, they put him in too early and he went in feeling he had to make a play rather than learning to just play within himself. The Bears are in a heck of a spot in that, my guess, they are best off resigning him. They have used so much draft capital on the QB position (the cost of that trade up really hurt them) plus trading a draft pick for Folds, that I don't think they can afford to go after another one. Plus as a potential playoff team, likey their first round pick is about #20. They really need to address other positions first and who trusts Pace to pick another after he has already messed up on three (Glenon, Folds and Trubisky). While the OL has performed better, I still question it. Even if they get rid of Pace, not sure the next guy is ready for that right out of the gate and there are so many potential holes, nto right time to go after a QB.Just when you think Trubisky and the Bears are getting somewhere on offense, he goes and throws an incredibly dumb interception in the Endzone at a critical juncture. Same old Mitch. Same old bears.
In short, I feel the stars are lining up so that their best alternative is bring back Trubisky, like it or not.
