OK, I could create a list of all the good things teams other than football have done since Tanner has been A.D., but obviously you don't care (to sum it up, every team other than cross country has made the NCAA tournament at least once during his watch, but I won't waste your time with all the various championships, Final Fours etc.) Football is the only sport that creates revenue at USC (men's basketball and baseball lose money each year - I asked at a Gamecock Club meeting a couple years back).
So football only: Assuming Muschamp and the Gamecocks beat Akron, Muschamp will have the most wins of ANY USC football coach in history for his first 3 years on the job. I think you have a false sense of our own history in football and think that somehow Tanner has destroyed a traditionally great program. 100+ years of Carolina football and only 4 years with 10 or more wins (and the 1984 season wasn't as great as folks would like to remember as USC lost to freaking Navy and lost its bowl game.) So tell me again what Tanner has done to put the department in the dumpster?
All of our women's programs are relevant, and I know you don't care. WBB is rebuilding, but they will be fine. MBB stinks this year, but still has a Final Four (even the great McGuire never got us there!). Baseball - definitely on the way up with the hiring of Kingston who was lauded by national pundits as a great hire.
If you're angry that MBB is having a bad year, that's fine. I think some of the players have to be accountable for that, too.
