Coming into today, only Iowa and Ohio State remain undefeated in the conference. If Purdue, Iowa, MSU win, and then assuming PSU wins, the top of the conference will look like
Ohio State 3-1
Michigan State 3-1
Penn State 2-1
Obviously a lot can change, but this would put Iowa, MSU, OSU, Penn State on top of the conference. And if it were up to me, I'd prefer Iowa go to the rose bowl, for obvious reasons. But it seems like with everyone's inconsistent play this year, anything can happen. Actually, it seems like Sparty has the easiest schedule remaining. The would have the advantage in tiebreakers since it's been 392 years since their last RB.
Anyways, it just seems the conference is up for grabs. Even for us, it's not out of reach.
