Yes he fumbled the ball twice, yes he got intercepted once today, but he did lead his team back to victory. He lead his team back to victory even though his O-Line is shit and his receivers dropped 7 passes. He lead his team back to victory from 14 down. So has Grossman taken that step to becoming an NFL quarterback? On the 2 fumbles, Rex did the right thing by stepping up in the pocket and showing some mobility. As for the interception, Berrian could have put more of a fight for it, but quarterbacks have to get picked off once in a while. And I guess it's acceptable if you haven't been picked off in your last game and a half.
Grossman will lead the Bears to the playoffs...
