Answer: We do not beat Ohio State.
I realize Oklahoma is a little over-rated, but oh my god, Ohio State looked like a freaking NFL team out there. We're not beating them and we should just go into that game thinking, "Let's have some fun and work hard and get better from playing THE best team in America right now." Keep in mind, if Nebraska shows the right amount of grit and determination, we could be going into that game against OSU as an undefeated top 15 team. That's a big deal, and we REALLY do have a team this year, but we're nowhere near OSU's level yet. Ohio State is a team full of athletic freaks, coached by the reanimated corpse of Alan Thicke's dead clone possessed by the infernal soul of Bear Bryant. Or something like that.
I agree too that Wisconsin is our big game. By the way, I don't think they will be ranked by the time we play them; they have to play Michigan State this Saturday (Loss), then Michigan (big Loss), then they are off, then Ohio State (huge Loss), then Iowa (50/50 at that point), THEN us.
If they can even field a team after that, I will be very impressed.
Still, playing in Madison really blows (loud, drunk fans), and Wisconsin is, in my opinion, our real rival in the Big Ten West division; they're consistently better than Iowa, and they really have cleaned our clocks over the years. And their fans know it.
