One other factor involved is who these teams play week 13. Both teams have to travel to a hungry/desperate opponent. It's likely both Illinois and Minnesota are 5-6 heading into those games, with both of them needing to win to get a bowl game. I think it's possible both Northwestern and Wisconsin lose. I'd actually think Minnesota has the better chance of the upset right now. If so, I think Northwestern is our best shot at keeping a ranked B1G West victory. I think it's entirely possible Wisconsin could lose both this week and next week. They haven't played a decent team since early October, and may not be able to win out.
