My Super Bowl Pick

I don't know much about football, but I did watch the playoffs after the Army-Navy game. My pick is Pittsburgh to win, by at least 6 points. I really am not up to figuring out a better point spread. (Just checked online oddsmakers to learn Pittsburgh is favored by 4 points). My rationale is that Steelers just seem bigger and heavier. Of course, we'll all find out what happens tomorrow at 3 pm Pacific Time...
