though this article is espn insider, the last paragraph gives us something to think about:

The big question is who should be chosen to challenge Johnson? Even with the aforementioned drop-off of the top contenders, there is one player who has more than enough to play the role of Optimus Prime -- Pittsburgh Steelers wide receiver Mike Wallace.

Most of our best players have nicknames, when you think about it. We have Big Ben, RushHard, Sir Isaac Redman, Silverback, Potsie, but Mike Wallace has yet to develop one. Should we refer to him as Optimus Prime from now on?
