Its really hard to say without giving criteria. If you start with 2000 I think you could make a case for Michigan, Wisconsin, Iowa, and Penn State to be 2nd all a long ways back of Ohio State IMO
3. (tie) Iowa & PSU
Now someone want to throw the Winning percentages in????
I thought you meant individual teams....of which I would have (in no particular order)
-2002 Iowa
-2002 OSU
-2006 OSU (got killed in NCG...but still amazing)
-2004 Michigan team (I think they almost beat the longhorns in Rose Bowl?)
Maybe 2004 Iowa team
And of course there are others that I don't feel like reaching into my memory to pull out...I'm sure a Wisconsin, and prob another team like that. And PSU teams too....maybe 2008? They were pretty dang good that year...
