Not likely Michigan loses two games (one being tOSU) through the end of the season (contingent PSU wins out), so next best case scenario is a Rose Bowl berth. Here's my checklist:
Week 9
Penn State beats Purdue - check
Wisconsin beats Nebraska - check
Ohio State beats Northwestern - check
Week 10
Penn State beats Iowa - 63%
Ohio State beats Nebraska - 86%
Week 11
Penn State beats Indiana - 75%
Week 12
Penn State beats Rutgers - 92%
Week 13
Penn State beats Michigan State - 83%
Michigan beats Ohio State - 56%
