Hard to say Mike. I mean what if Nebraska goes unbeaten. I know they struggled last weekend, but they still have Miami in the non-con, go to MSU and go to Wiscy, plus the Big Ten championship. If they go 13-0 I think it would be hard to keep them out (now granted I do not think they go unbeaten, but what if).
If Michigan State rebounds and wins out and does so convincingly, I think it would be hard to keep them out because after-all it was a road game and they were winning for much of the game (they did get rushed a bit late, but they were still up 11 in the second half). I mean even Ohio State can't be ruled out entirely, especially if Virginia Tech is unbeaten when it goes to the ACC Title game. OSU had a freshman QB that wasn't supposed to play at all this year and he played like it.
Just too early to rule out the conference as a whole, but clearly the conference needs some good fortune to go its way.
