FWIW I don't totally agree with Nelson's view but I do think that anyone who doesn't think basketball will take a hit long term in the American is either intentionally ignoring reality or hasn't a clue. UConn could still compete at a decent level, but forget about really deep runs.
As far as attendance goes, I think a few things have happened. First and foremost on the football side the team was awful. A cold December day, with a game against an equally awful Memphis team was lucky to draw what it did. On the other hand we also set a record for Michigan, and drew well for Maryland and a solid crowd for South Florida, considering that was 2 awful teams too. On the basketball side, the NCAA has created a monster with its tournament. For power teams, with the exception of a handful of "big games" against top opponents, the regular season is little more than an exhibition season where power programs ring up there requisite 20 wins to get tickets to the real season which begins in March and lasts about 3 weeks. Nobody cares about UConn-Houston since it is just one of those ticket-punch games that counts toward the 20. Its worse for UConn in a sense that nobody knows or cares about most of the teams in the AAC, but even Duke doesn't sell out most games any more. Rutgers had under 500 at a game. BC which used to draw reasonably well, had around 1500 for one game and 1200 for another. 3500 (in an 8300 seat arena) for a conference game against Maryland. Add that virtually every game is televised somewhere, in HD, with lots less hassles, cheap beer and nachos, the fact that for a decade or more, the UConn athletic department pretty much treated the fans as an ATM and nothing more, and basketball regular season attendance is never going to return to the 1990-2000 levels. with a good team, football could return to the Edsall era level, in part because its only 6-7 games. One final note, is that UConn has pretty much tried to build a UConn fanbase. Good concept but as the seasons have more and more started to overlap (the Dream Team's first game was Nov 24 and first home game was Nov 30, the 1999 National Champ's first game was Nov 15. this season started November 8) the demands on fans become impossible unless you commit your whole life to attending UConn athletic events.
