I am intrigued by the notion. However, this seems a little backwards. If the team wins, I feel good and don't need any extra perks to make me happy about the win. Why not take a page from Mbakwe's book, guaranty a spot in the NCAA tournament, and refund a significant portion of ticket costs if the team is sitting at home in March?
It reminds me of my buddy (a good guy despite being a Michigan fan) who went to the Rose Bowl and bet the whole cost of the trip on the Wolverines to win. Then they lost and he paid double for the trip. He said to me, "I was an idiot. I should have bet on USC. There is no amount of money I wouldn't pay to go see the Wolverines win a Rose Bowl, and if they lose, then I would have at least gotten a free trip out of it."
