I've looked at this issue in depth through the years. BCS bowls have guaranteed payouts because of the TV contracts. Non BCS bowls obviously don't have the lucrative TV contracts and I am 100% positive that the noted payouts for all minor bowls include substantial money based on ticket sales. Depending on the school and how they are required to share revenue with the conference is a totally different subject.
The reference to UConn is in regard to the Fiesta Bowl. The Big East was paid 17 million for UConn making the bowl game but per the revenue sharing plan only received a small portion of that.
The below excerpt is from the school paper. Please note how much they "lost" because of unsold tickets. Keep in mind this is a BCS bowl. So you know good and well if the BCS bowls count ticket sales towards the revenue payout that the small bowls do as well.
The university incurred total expenses of $4,280,998 at the Fiesta Bowl while only receiving a payout of $2,523,200 from the Big East. By far the largest expense the university incurred came from absorbed ticket sales. The university sold only 2,771 out of an allotment of 17,500 tickets, resulting in the university absorbing 14,729 tickets worth $2,924,385.
