I can point to maybe a half dozen decisions that fall into that category.
Tearing down the goalposts after beating Houston in '97 was try-hard. The tiny, original video board in M.M. Roberts was depressing. The 9/6/99 promotion was a bad idea. Giving the head cheerleader a microphone in '95-'96 was the act of a braindead man. Trying to twist Tulane's arm into making a trophy for us to contend for came off as desperate.
The common theme in all of it is that the people in charge are tone-deaf when it comes to what Mississippi sports fans actually care about. We don't give a shit about beating Tulane or LA Tech. Having some low-IQ hick male cheerleader exhort us to "get loud" will have the opposite effect. Nobody cares about winning some laughingstock conference that doesn't even have an exit fee.
My best USM memories are the times USM went head-to-head with truly relevant teams. Many of those games were losses. Some weren't.
The ethos was "Anyone, Anywhere, Anytime," and that's not that far away from the "P6" shit the AAC is doing now. Wish USM could be a part of that. There was a time, pre-Pizza Bowls, when that suited USM.
As for the "TTT" cheer, I can confirm that more than one person sitting next to me at M.M. Roberts has used the exact adjective you did.
