Why did they pull him?
They pulled him because the game was a blow out. The score didn't give the game justice in terms of how one sided it was. Tim GRaham on ESPN even mentions it... Belichick basically threw up the white flag by pulling Brady, saying "I give". And Peyton obliged by calling off the dogs. Belichick's secondary was in tatters and what the FCK would you leave Brady in for? So he can get hurt again? The game was over.
