Yes, Michigan can beat Penn State on Saturday night in Happy Valley. No, it's not impossible. Not completely far-fetched. Not out of this realm.
But, right now, the "ifs" appear to have it.
When you start going down the list of things that seem necessary for the Wolverines to pull off an upset at No. 2 Penn State on Saturday (7:30 p.m., ABC), you wind up with one conclusion.
It feels like a long list.
If the defense plays up to its potential, Michigan has a chance. And if the offensive line can carry over its performance from last week at Indiana -- and erase some earlier hiccups -- those chances improve.
