He used that facemask which I think it looked the best on him (like a true RB) until sometime in the 2011 season. However he wore this for a very brief time Then wore a facemask that's not common for running backs, he started wearing it in the middle of 2011 season before the ACL/MCL injury. Despite that, he went on and ran like a true MVP, nearly broke the NFL record. Still don't like that on him, though.
