The way Blake Corum sees it, the Michigan Wolverines are unbeaten, top-ranked and two wins away from a national championship because of all the turmoil they've overcome this year, not in spite of it. Michigan's star running back explains his view while sitting among his teammates Saturday under a big white tent outside the rain-soaked Rose Bowl, where the Wolverines (13-0) will face Alabama (12-1) on Monday in the College Football Playoff semifinal. “I think we learned from all our setbacks, all of our mistakes,” Corum said.
