A lot of great wins in my years of watching basketball, my view time has been from Eldon Miller's last year as coach, till now.  i have never watched OSU celebrate a National Title in basketball, an NiT Championship sure, but never "the Big One".  Over a span of over 900 games, My favorite to have watched is:

1. 1991 vs Indiana, in Columbus.  A 97-95 overtime win.  OSU had a great game by Jim Jackson, and a few clutch shots by Treg Lee....Indiana had Calbert Chenney, Eric Anderson and Damon Bailey.

2. 1992, either win vs Michigan's Fab 5, with all the publicity, you would think the Fb 5 never lost a game.

3. Almost every game of the 2007 NCAA tournament....Tenessee and Xavier.  The loss to Florida ( I refuse to remember) withstanding.
