Because I live in Pittsburgh I've watched this team all year - it just seemed the Steelers caught just about every team they played at the right time. Their road schedule was really really weak. Every tough game they played was at home - it almost makes you believe in destiny (which I think is crap).
I will give them credit for beating the crap out of NE and Philly - both at home. But c'mon, how nice would it be to be in a division with Clev and Cin. Plus they played the NFC east - probably the weakest division this year.
Given all that though, I think they beat NE, not because they are a great team - but because of the intangibles (the crowd, maybe Bettis's last game, being the underdog - which they are really playing up, etc) - plus they do have a better running game than NE. If they can keep the ball from Brady and not turn the ball over more than once I think their running game will wear down the NE defense by the 4th qtr.
