Just b/c New England took care of Indy in an overwhelming fashion doesn't mean they will just as easily do so against the Steelers. You can make an argument that Manning/the Colts can't play outdoors, especially in January, especially in the snow and you can even take it one step further and say they just don't have what it takes to win the big game.
The Steelers last game was ugly. But it was against a team that confused the hell out of them earlier in the season. The Jets had the Steelers number, they should have won that game, but they didn't. Last time I checked, the Pats did NOT have the Steelers number. In fact, they got blown out during the first half of their meeting earlier in the season. Second-half scoring by NE didn't mean much, b/c the game was pretty much over. Ok, so they didn't have Dillon. But one thing everyone is forgetting, the Steelers know Dillon. He played on Cincy all those years, which is in who's division ... oh yeah, the Steelers. That's two games a year Cowher and Co. have faced Dillon. So the game rests on the hands of Roth. If he completes 60% and throws for more TD's than INT's, Steelers win.
By the way, NE will win, I was just trying to make a case for you Pitt fans.
