That depends, Ricador. The Steeler's did have the 100 yd. touchdown run, which I think takes some serious skill. If the Cardinals had run it an extra yard, they would have been in the lead, and probably could have held it.
I dunno, i just don't like the Steelers because they stole the SuperBowl from the Seahawks. Everyone who saw that game on both sides agreed that was unfair >.>
