Minnesota Vikings running back Adrian Peterson admits he was a bit rusty after missing almost a full year of game action and wasn't at his peak conditioning. After back-to-back 100 yard games, he now believes he's back to being the old A.P. "My legs felt lighter today and just the preparation throughout the week helped with that, but I felt good," Peterson said. "The body felt good. My mind was in a great place, and yeah, I think I'm back … The biggest thing is, I would make sure I'm just in position to make sure my lungs are open.
