In retrospect, neither of today's outcomes should be that surprising. Minnesota has no bad losses still and Ohio State's (and Michigan's) win over North Carolina looks increasingly unimpressive, of course..... Likewise, I'm not sure how good Purdue's wins over VCU and Virginia are while Nebraska's losses to UCR and SUU really aren't as bad as you'd think in retrospect.
I wouldn't even be that surprised if Northwestern upset Sparty to complete the sweep of first conference home games.....
I still think the Buckeyes are probably the best team in the league, but this season is going to have a lot more parity than usual it seems....
