He's the type of guy that can flip the switch probably better than anybody. He can be in here warming up with the guys and jackin' around and then he goes out there and crosses the line and, bang, he's all business and trying to win the drill. One minute he's putting ice cubes down a coach's back, and the next he's throwing a touchdown pass where he's totally focused on what he's doing.
