When you go 18 and 0, you only change one thing: You do go for the field goal early in the game. IMHO, it was arrogance not to do so.
However, before the game, I just "knew" the Patriots were going to win. I was thinking 47 to 3 or such. The Giants weren't even supposed to be at the Superbowl, unless they had a ticket. But, I can only congratulate the Giants. They won it fair and square. In fact, on the day of the Superbowl, they outplayed the Patriots. Period.
Now.....Having said all that.....Does this mean the Giants are a better football team than the Patriots? No.....I mean hell no! And if these two teams met again next Sunday and you had to bet $1,000 on the winner, who would you take? I'd take the Patriots, without a second thought.
