Serena and Matt talk Michigan-Michigan State, what makes this year's version of Sparty particularly unthreatening, logic vs. emotion, and the "Harbaugh remembers" mantra, then briefly revisit the Indiana game (which was basically the Rutgers/Nebraska/Minnesota game, just with the eventful stuff in a slightly different order) and debate whether it's Penn State's or Ohio State's weaknesses that turn out to be fatal this week.
