I really think that if we beat Wisconsin, we're in.
The Big Ten is the 2nd best conference in the nation. Winning 10 conference games, 3 of which came against the Top 4 teams, has to be enough. Furthermore, beating Wisconsin would have to put us in ahead of Minnesota, who according to most experts are still in ahead of us right now. But if we beat Wisconsin, there is just no possible way you could put the Gophers in ahead of us.
