There are lots of ways you can give out MVP awards. But if you put the emphasis solely on the value a player had to his team, Freeman wins in a landslide.
More than anything, Freeman used his back to carry the Buccaneers. Tampa Bay had the league's lowest payroll and had the youngest roster in the league and, if you really look at that roster, it wasn't all that good. Yes, some bright spots (running back LeGarrette Blount and receiver Mike Williams) emerged, but part of the reason they emerged was because they were playing with Freeman.
