you've based this one entirely on the performance of these two teams in one game. Over the course of the entire season the Giants looked like an average team at best (even some of their victories were awful)
So did the Pats. Their win against the Ravens only came because the Ravens handed it to them on a platter. There were many games the Pats were lucky to walk away from victorious.
Nothing wrong with that - every pitcher who throws a no-hitter is the beneficiary of at least one stunning defensive play to keep it going - but all this talk about them being The Greatest Team Ever (or anywhere near it, which some of their fans are still proclaiming) is highly dubious at best and laughable at worst.
They didn't even play a close game until their victory over the previously-undefeated Colts in the ninth game of the season, and over the course of the entire regular season and playoffs they played only five games (four in the regular season plus the Super Bowl) in which they failed to win by at least a touchdown.
Their AVERAGE victory margin of about 20 points per game wasn't much less than the Giants' TOTAL point differential for the entire season (+22 points).
What really galls other fans-and this is the reason almost all of them, including those who supported teams that had lost to The Giants previously, were rooting against The Pats-is the unjustified arrogance.
Even now, after the biggest choke in the history of the NFL, you can still find Pats fans who are making the ludicrous argument that their team is somehow superior to the undefeated 1972 Miami Dolphins.
To compare Tom Brady to Joe Montana, or even more absurdly, Bill Belichick to Chuck Noll or Vince Lombardi, exemplifies the self-absorption of Patriots fans, IMO.
