Most Dominant Year: 2006

Once upon a time, the Vikings QB was one of the best signal-callers in the game, a 6-4, 260-pound bundle of size, speed, strength and passing ability. Then, he landed on the cover of Madden 2002, and it's all been downhill since then. He was actually a devastating player in that game, an almost untackle-able force in the open field with a dangerous arm to boot. But in reality, he suffered a rash of injuries after making the cover, and by last year, his NFL career was no more.
