There's no arguing the fact that Auburn's offensive life force is its running game. That's how head coach Gus Malzahn has always wanted it, and that's how offensive coordinator Rhett Lashlee plans it out.
From east to west, north to south, Auburn's rushing game is the heart of an offense that can sometimes survive with a one-dimensional look more than most.
So if the run game pumps the blood, Kamryn Pettway acts as the lungs. He pumps oxygen into this crazy thing, and without him ... well, there isn't much of an offense to find in a crunch.
