For the most part, I agree with what AADP and Akamp said. AADP's points are insightful and logical. Akamp's words were very inspiring and get me psyched.
But, for me I think the point really comes down to the fact that I don't believe in the myth of momentum in football. I just don't. Analysts talk about it all the time, but just watch how easy it is for the losing team to totally turn the tables on one play. One play can change the whole energy of the game. That's not momentum, as momentum by definition takes time to build up. So, if there were such a thing in football, the Packers would have it right now, with 5 wins in a row. But I just don't believe it, because in the NFL, fortunes can change in the blink of an eye, with one play.
Now, what I do believe in is the power of fierce desperation. This is what makes me worried about the Steelers, regardless of the logical argument laid out by AADP. I'm worried about the Steelers coming together and having a "come to Jesus" meeting like the Packers did after the Tampa loss. We came out the next week with nothing to lose, and a team with nothing to lose is a dangerous team. Honestly, after the Tampa loss and the "come to Jesus" meeting (man, i love that), Dallas didn't stand a chance in hell! So it's not that I think the Steelers are the better team or that the Packers will not be prepared, but the desperation that I'm sure the Steelers are feeling is the wildcard in this situation. That specifically is what worries me about this game.
