You're kidding, right? You've played 3 currently ranked teams. Ohio State, Wisconsin, Notre Dame.
Wisconsin is 11-1 and hasn't yet to beat a currently ranked team. Yep, they have not beaten a team currently ranked because they've played crap teams. It's a mystery to me why they're even in the top 10.
Notre Dame. Need I say more? One of the most overrated, overranked, overrhyped, overtelevised teams of all time. Why? Because 30% of the people in the US are fans simply because of religion (fans=$$$). They got blown away by 2 ranked teams. Only beat #25 Georgia Tech. Almost lost to UCLA and Michigan State. Terrible team. LSU will dominate them.
Ohio State. Michigan was outclassed. Michigan led ONCE in the entire game. That was after the cointoss had them receiving the ball. OSU tied it soon after, 7-7. Never trailed since then and led by double digits the majority of the game. The game was closer than it should have been because of UNforced turnovers (2 bad snaps and a deflected pass). It should've easily been a 18 point blowout, but a desparate pass by Michigan's garbage QB got them to 3. End of game. Michigan didn't stand a chance (and I don't want to hear about neutral field crap arguments).
Florida lost by 10, but another deceptive score. We led the game for more than half the time. Key: we didn't allow a single offensive TD. A bad call that said "fumble" screwed us. It was a 4 point lead for Auburn with time expired, but our laterals were still live and a Auburn ran it for a TD.
As far as wins...I think you already know how many ranked teams we've beaten.
