Wisconsin has already signed their ticket, but who is going from the Eastern Division? If it ends today the team would be Ohio State with only one loss. Three other teams, PSU, MSU and MI, have two losses. So for the sake of argument let's say Michigan beats OSU, then four teams could possibly be tied for the division lead. In that scenario...
Penn State beat Michigan, and lost to OSU & MSU
MSU beat PSU and MI, but lost to OSU and Northwestern
Michigan beat OSU (hypothetically) but lost to PSU & MSU
OSU beat PSU and MSU (48-3!) but lost to Michigan and Iowa
Who would go to the Championship game?
