I know you have choices listed CL82, but with the Price is Right rules I am going to go with the answer of 1 fan in the same way contestants guess $1 as they think the other contestants have gone over the actual prices, or attendance in this case. It wouldn't surprise me in the least bit if attendance was below 5,000 (actual) and I end up the winner and I don't say that with happiness
As for announced, the PA announcer can say any nonsense like 30K or whatever so I am forfeiting that part of the game.
This game in an odd way is bigger than BCS Championship as UConn football is fighting for survival. If they lose to Holy Cross, oh my, the chorus for ending the football program will be deafening. Am I being hyperbolic? Probably, but this game is huge-UConn has to win convincingly.
