Harvin would have been the worst ever. Had he been inactive for the game, no one would have noticed, and there would have been no real effect on the outcome.
Wilson played very well. and he made a difference between his his team scoring over 40 and over 25. Again, he didn't affect the outcome much at all. Only if the award was required to go to a player of the offense would I give it to Wilson.
The defense dominated the game. I would even have considered Sherman (with no stats) other than shutting down half the field. However, there were others who were more deserving than Sherman. Acril is my choice.
