The Patriots are the best team the NFL has seen in a long, long time. They always get the job done.
It doesn't seem so long ago that the Giants and the Pats met during the regular season. The Patriots could have rested their starters but didn't. Good for them, since they could have easily lost to the Giants who played a pretty decent game.
The Giants have been as hot as any team in the playoffs, which is why they have earned the right to be here. Eli has demonstrated that he has what it takes to bring a team all the way, and the Giants have a great group of wideouts. Imagine how much more effective they would be if they still had Shockey and Barber! Point is, Eli has nothing more to prove to anyone and can hold his head up even if the Giants loose today.
Nothing is going to stop the Patriots from making history, they will finish this season without a loss. But the Giants will do everything in their power to stop that from happening and IMO this will be a close game at the end.
