I think immaturity and discipline played factors. Immaturity in the young QB's, and even in some of the guys they need to step up and make plays like Jackson/Golloday when they dropped balls.
Discipline is kind of the same thing we've seen in the Muss era. Personal foul penalties.....missing tackles (I'll throw that in the discipline of making a tackle), and even a play like Bartels not sliding and fumbling the ball away.
The more mature and disciplined team won the game. Despite their coaches not running the ball in the fourth quarter for whatever reason.
