Maybe you haven't been paying attention, but I've been saying this since that embarrassment of a season finale by ALL INVOLVED, including the defense and ST's. When you as an offense have 5 runs for 0 or negative yards, dropped passes, stupid penalties, a lack of TE's, and a missed FG, it's obviously more than just about the QB. And that's not even talking about the performance of the defense and ST's.
In theory, it's "easy." However when you're dealing with a 2nd year QB who missed most of his 1st season with a broken leg, the reality if it's far from "easy."
They DON'T know. That's why JP is already in Buffalo. Hopefully JP shines and makes the decision a correct one because, whether one likes the move to dump Bledsoe or not, it's done and we have to move forward. But to blame the problems on offense on Bledsoe is ridiculous. That's the reason why the Bills will be focusing on improving the O-line, getting healthy/better TE's, and finding a dependable 3rd WR. But guess what? Those things would have helped Bledsoe out a lot this past season as well.
