If one of those teams played someone else, obviously the game would have been different. Had the Pats played the Saints, I don't believe the Saints would have only scored 3 points, but it is also unlikely that NE would have only scored 13. Maybe the Saints could have won, but I would have still bet on the Pats in a higher-scoring affair.
When the game was over, I told a friend that I wouldn't be able to listen to any commentary about the game because it would all be about how dull and boring it was. And all because it wasn't 55-51 and a see-saw game. To me, it was the best Super Bowl I remember in many years, simply because the yards and points were so hard-fought for. I had no "team" in the game, but I was pulling for the Patriots because of my distaste for some Rams personnel and the way they got there.
