Sheldon Brown's hit on Reggie Bush in last year's playoffs.
"He was lucky," Brown says. "His elbow was pinned against his body, protecting his rib cage, or else I probably would have broken his rib. What did it feel like? That collision, I didn't feel nothing, because he was pretty much defenseless. It was like running through a cardboard box. Seriously. Cardboard box."
