Who should've been MVP of the SuperBowl?

Eli was by no means the most valuable player. They only dropped 17 on the Pats D, which is average for the Pats D. We all know that Wes Welker was the Pats MVP if they had won. I say that Justin Tuck was the Giants MVP. However, should the MVP always be for the winning teams QB? in SuperBowl V Chuck Howley was MVP, even though the Cowboys lost. Should Welker's record-tying 11 catches?
