Quarterbacks are judged by two things in the NFL: their talent and their leadership. Both are required if they aim to not only rank among the best ever to play but also win a championship.

He must learn to play the position like a professional. More importantly, he must get a Chicago Bears locker room full of grown men to believe he is the guy they need to win.
