I gotta say the Steelers. 3 straight weeks, on the road, beat 3 top AFC teams. I don't think it's possible to do that same task AND lose the Super Bowl. It's just not. I'd be shocked if they lost.
The game would probably be close, because The Seahwks have a great offense, led my the MVP and leading rusher, Alexander and Seattle can get pressure without blizing.
Well you know what they say, Defense wins championships. Pittsburgh has the better D, so they win.
