I'm not sure. I think that in both super bowls the Patriots had better players on the field than the giants, particularly at quarterback. While I think Belichick is probably the best head coach today, he was outcoached in those games by a good coach, who used to work with him. Sure. the Giants had some luck late in both games that was crucial, but it was finding a way to stop Brady that put them in a position to take advantage of good fortune.
