Well, here's my perspective. If the Steelers win they get the record of times to win the SB, if the Seahawks win, It'll be their first time, so either win will be interesting. But Seattle, I really wouldn't get your hopes up. I mean this sincerely when I say you should be really happy to have made it this far. I really don't care who wins, but as a nonbiased spectator, I think that Pitt has more aggression, more skill, and better players. I am not going on stats, cause I don't know any, but if Seattle wins I will be very surprised.
I don't know who I'm gonna root for. I usually like the underdogs, and that would put me with Seattle (IMO), but Pitt has come up from the sixth seat position so in a way, they are underdogs also.
