short version, purdue and ill are already eliminated effectively. for those left (which we need them all to lose once, unless we beat OSU somehow)
MN: Ill, Pur, OSU, WI
IA: NW, RU, Ill, Neb
NE: MSU, MD, WI, IA
WI: IU, NW, NE, MN
NW: IA, WI, Pur, Ill
So given that, and given we still play WI of those listed, I'd cheer for NW this weekend given I think they'll lose to WI and we can take WI out to end the year for all the marbles. Plus cheering for iowa is always gross.
Based on ESPN projections, NW is still projected to lose out. MN to go 2-2, IA to win out, NE to go 1-3, and WI to win out.
