Steve is the best I've ever seen play the position, and I was watching when Rice was prime. No one has ever played like Smith. Other guys may have better stats, but none could do so much with so little.
I have 2 plays: '05 @ CHI when he stops on a dime, safety plows into the dirt and Steve hops him and strolls in untouched. '08 vs the Giants when he gets creamed in the endzone, shatters his arm, and hops up with the arm flopping and don't give a ****.
