As far a my eyes tell me it's...
1. Ohio State (far and beyond any team ranked 3-14 in the conference and maybe even Wisconsin)
2. Wisconsin (for now)
3-10. Anyone could beat/lose to anyone within this group I feel and really is no difference.
11. Minnesota
12. Rutgers
13. Michigan State
14. Illinois
Those last 4 teams are bad. Really bad. There is no excuse for Nebraska to lose to Minnesota or Illinois.
