Oh, this is awesome! I hadn't seen this before. Too cool for all these folks to do this. They're raising a ton of money, and all for a great cause. Thanks for sharing this!
The one that stands out to me is "Mark Cuban, One-Day Contract to Play With The Mavs". How awesome would it be to go into a game for a few seconds and score! I'm a pretty dang good shot. I think if they gave me at least 3 chances at a 3-pointer one would go in. I'd say 2 chances, but I'm sure the adrenaline rush of something like that would be pretty good defense!
