Awesome Sports Idea

I have always thought it would be a great idea to have some type of exchange where you could buy and sell sports teams like stocks.  For example, say you want to invest in the New Orleans Saints because you think they are a great team, possible super bowl contender, and you know they play some cupcakes in the next few weeks you might want to invest in the team at current selling price of say $100/share.  After they win realistically the next five games their value would increase because more people would jump on the bandwagon.  Sweet idea and if you know what you are talking about like I think I do, you would make a lot of money $$$
