This could go either way. The Giants beat the most powerful offensive team ever when they beat the pats in the 2007 sb..however, just 2 weeks before that, the Pats laid 34 on the Giants at home, pretty easily.
I say Giants win. Low scoring game.
um, no... that's really not accurate. the niners championship offenses (and the dallas teams of the 90's) were much more powerful because they controlled the game. the flaw with the pats, as with every other team that has a "big play" based offense (just like the colts won when peyton handed the ball off more, not when he was throwing records) is that they cannot control the flow of the game. they score a lot, but don't control the game. note that the offense was not powerful enough to win the big game.
the niners west coast offense controlled the game in any which way they wanted. classic examples of bill walsh saying to jerry rice or brent jones or john taylor,"i don't care if you can break one, just get 4 yds and go down" exhibit what true dominance they had. unless you own the clock, which the niners did, you're not a complete offense.
The saints will experience the same problem as the explosive, but imbalanced, offenses of the colts and pats record setting years.
