....we have a lackluster performance against USC and Michigan curb stomps OSU and Northwestern. As vile as that is (not to mention highly unlikely -- I actually think the OSU-UM game is a toss up, though UM will prob win), I do think there's a lot of anti-ND bias on the Committee, and they'd overlook the H2H in favor of UMs Conference Championship and style points in the last two (plus if UM blows out NW, it has that "common opponent" neutralized).
Just being Devil's Advocate here: these things are highly unlikely to occur. For one, Georgia is NOT beating Alabama!
