It might be more advantageous for Ohio State for Penn State to win, as I think they are getting into the playoff regardless of who wins between a Penn State / Wisconsin match up. That being said, I like to be able to control our destiny, so I'd prefer just to get to Indy, win it, and be assured a spot.
Ohio State looked awful on offense for 3 2/3 quarters. Though, Michigan's defense is good, and good defenses have a way of making offenses look bad. I think it says something to play terrible for most of a game and then still win. They definitely aren't clicking on all cylinders, but even with a hole in a piston they still look decent at times. I'll take it.
