It seems as though things are going fairly well in Adrian Peterson's recovery from left knee surgery. At Minnesota's Winter Park facility for the start of this year's offseason team activities in late April, Peterson noticed that his teammates weren't running that hard. So Peterson challenged those same teammates to a footrace and won easily. "He was off to the side working with our trainer, Eric Sugarman, and he looked out and saw the guys doing their wind sprints," head coach Leslie Frazier said. "He says, 'You know, I don't think they're running hard enough.' Eric allowed him to go out and run with them, and he passed them four different times. He finished in first four different times."
