I look at the whole thing like this:
Cutler, by the numbers, is still the best QB the Bears have ever had since Sid Luckman, and a few more years with the team, he'll break those records too.
Is he perfect? No, hardly. But talent-wise, he has everything a person could want - a prototypical QB. The questions are his mechanics and decision-making, and being real, its really just decision-making, because no one is going to give a shit about how you get a ball somewhere as long as you get it there.
Anyone with eyes and has payed attention to the team when Cutler plays knows he plays his best when he has blocking up front, and his receivers are making grabs and moving the chains. Seriously, that should be a no-brainer because football is a team sport - no one can do it all themselves.
However, when his supporting cast goes south, his line starts falling apart, receivers are dropping routine balls, etc - thats when Jay goes into "bad decision mode" and tries to win the game all by himself, usually leading to that rash of poor decisions that ends up screwing the team.
When you look at it like that, you realize its all mental. Thing is, Jay can throw a pick and bounce back. He's done it before. Where he really gets fucked up in the head is when he gets no protection. It ends up affecting him the whole game. Not just one bad play, but when he's on his heels for an entire series.
What this also means is with the attention paid to getting him real line help this year (in the form of players and coaches), and giving him weapons to use, we might finally see Cutler with a higher floor than years past, as the pressure to win it all by himself hopefully won't rear its ugly head.
