It's not an officially sanctioned NBA event, like the Dunk and Three-Point contests, but it will be aired by TNT on the Saturday night before the game. (That's February 14, in case you were wondering.) It will also feature bona fide professional basketball players, although the participants haven't been named yet.
But if you've always wanted to see Tony Parker force Vladimir Radmanović to bounce a free throw off of Ernie Johnson's head, then your prayers have been answered. It also has nothing to do with this video of Kobe Bryant riding a horse, although that seems like it could be fun too.
