Tom Brady choked. A backup QB who was ready to retire and become a pastor was slotted in a great team, and the team won the Superbowl. Another example, Noodle Arm Peyton Manning was slotted in a great Broncos team, and they won the superbowl. There are plenty more examples.
QB is the most overrated position in all team sports. The position doesn't even play all phases of the game, and yet, gets all the credit for the win. Nick Foles wins, "He was such a great QB. he deserves MVP."
But let us look at the flip side of the coin, Tom Brady lost, so why is it the defense's fault? If Tom Brady hadn't fumbled, and the team had won, nobody would be talking about the defense. LOL
