I was actually directing that at the OP... Since I know he's a huge fan, I'm surprised he'd vote for CJ. That curse is real.
Players never do well when on the cover. Eddie began the Madden covers in 2000 (Madden 2001). He actually had a career year that year, but sucked miserably after the murderer took the ball from him and killed our Super Bowl dreams. Not sure what the exact rule of the curse is. I believe Eddie and Shaun Alexander both had great years while on the cover, but sucked afterwards. The rest, I believe, sucked during the season they were on the cover.
