OK, those attendance numbers are flawed because they do not reflect the venue and several other factors.
1. The Sacred Heart, OSU and FSU games came as the 90 game win streak was reaching its climax. Also the OSU game was at MSG in New York. Those factors drove attendance for those three games way up.
2. I'm guessing the HC, LSU, Howard and Lehigh games were in Storrs, where attendance will always be lower, regardless of who UConn is playing.
Here is the reason you will not be able to get me to buy your argument: if you compare the best UConn opponent games in recent years to the best games say 10 years ago, at the same venue, I think you will see at least a 20% decline. The games against Duke, Tennessee, etc. were ALWAYS sold out 10 years ago, but in recent years, the games against Baylor, etc. have not sold out. And that 20% decline (maybe more like 30%), IMO, can only be explained by the major factors I am talking about: the economy and the aging/movement out of state of the fan base.
Same thing with the cupcakes. I think you will find a 20% decline, or more, in attendance figures for the cupcakes over that 10 year span. I remember very close to capacity attendance at Gampel back in the old days for all games, including the cupcakes, but that is no longer the case. And the decline IMO is due to the same reasons: lousy economy and aging/displaced fan base.
