Our attendance and fan support was the same here as anywhere else before the AD took a bat to it's knees. 35-40k in the stands was normal for even a half decent D1 opponent. It would have grown by more if not for the worst possible downward spiral anyone could have imagined.
During the last years of Ollie, and the first of Dan Hurley, the basketball attendance/fan support were terrible. We saw record low attendance. It was a pretty common topic here on the BY. It can happen to anyone who isn't at least competitive. It has nothing to do with people in CT just not caring for football.
The program won (iirc) 11 games over the 5 years before the 22 season. LSU fans wouldn't have showed under those circumstances either. And it wasn't just the lack of wins... it was the way it happened. Most games it looked like they couldnt get a snap off. It was like 3 year olds playing against the baltimore ravens. It wasnt just losses, it was losses to terrible teams by 35 points. No program could have survived that without taking a huge hit in support.
All they need to do is win a few games for a couple years in a row. Just be competent for a couple years, and it will be similar to before. We are not unique here. We will support our teams more when they win than when they lose...and almost none when they are the worst team in the country by a large margin (which we were).
