When Grossman catches FIRE (tied for the most games with a QB rating of 100 or more @ 7), the Bears win by 40.
When Grossman plays safe (QB rating over 50), the Bears win by 20.
When Grossman plays like me (QB rating of 40 or less, leads the NFL @ 5 games), the Bears lose.
He's not there to manage the game. He's not there to win the game. He's there to play a role and not hurt the team. He has a great surrounding cast to rely on.
