Suh was the winner for anyone who follows the guidelines in casting their vote.
He won't win:
http://stiffarmtrophy.com/He's already won the Outland, Bednarik, and Nagurski awards (becoming iirc the 4th player to ever sweep them) and the impact he had will not soon be forgotten. In fact, I think it will play out much like Tommie Frazier -- finishing second in the Heisman in 1995 (when he was clearly the best -- Eddie George? Really?), but having an impact on voters down the road, where they realized that qbs without the gaudiest stats might actually be the best player (Tim Tebow, and (although I didn't think he deserved to win) Eric Crouch).
For fun, here are the stats of 3 of the top defense's starting DLs, compared to Suh:
