If this was a home game at noon or 3:30, and Wisconsin wasn't borderline top-10 (and could very well actually be top-10 again in two weeks), I'd be more worried.
But it's not. It's a night game, on the road, against a highly ranked opponent in a hostile environment. Yes, their defense has looked great so far, but they haven't seen a team with a scheme or athletes (minus LSU maybe) like ours. We were at one point worried about running the ball on Oklahoma's defensive front, too - we all know how that turned out.
Urban and co. will have these boys ready to play, and a team that is still full of hungry young guns will come out still wanting to prove to the country that they are for real. I see a big road win. Go bucks.
