I don't see anyone beating the Saints. The team that will have a chance (when it counts) is the Vikings with thier abilities to sack and disrupt the QB...even then no guarantee? If Brees isn't pressured and or sacked, then he and that offense basically have thier way.
The only other way to stop this type of offense is the way the Pats stopped the similar high-powered Rams offense in SB XXXVI. The Pats beat the snot out of Warner and his receivers coming off the bus, in a way that todays rules protecting and benefiting QB's and receivers don't allow. Players would be jailed playing the way the Pats D- did back then. But I sure loved it!
The Giants similarly did this, even within todays rules, to the Pats in thier SB...I just don't see a defense out there like that Giants D- that can repeat that type of performance?
The Colts can bring some QB pressure from the ends, are gutsy and have some experience but are clearly, like every other AFC team, or any team for that matter, a notch or two below the Saints. Colts are a team that more resembles what they should be...a team with maybe 3-losses?...not a dominant undefeated team like the Saints are. The Saints, in a statement game for both teams, destroyed the Pats. A Pats team that looked like the better team for much of the game against the Colts... despite the wacky loss.
