Can you stop brady? no
you can only hope to contain him.
Can you out coach BB and hope he has a bad day coaching his defense? no
Can you stop a rookie running back who has not really proven himself through years of NFL dominace? yes
So why dont we play on that and strengthen our defense.
They know other teams dont have peyton manning, but they also know, that teams that cant stop the run will not win a super bowl.
Sure, a lot of teams have a running game, but the patriots have a running game a passing game and a coaching game.
The colts know that if they are the last team standing in the AFC, they have a really really really good chance of winning the superbowl.
The key to the colts winning a super bowl is having a good run defense. They dont need to dominate, why? because they have peyton, but they still need a good run defense.
EDIT: oh yeah we dont have one good running back we have 2 good running backs.
