Think the big ten is sure of 6...Michigan is the one on the fence
Ohio state has a lot to do.
Ohio State is in big trouble. Their overall rpi is down to 78. Only quality wins are Michigan and Kentucky. They are 2-8 vs top 50 and a feeble 3-8 vs top 100 and they only picked that third up because Penn State has now snuck in the top 100 rpi at 99. Buckeyes absolutely need to beat Iowa AND win at Michigan State
