Fuck David Beckham playing soccer in the States, Ryan Leaf playing football for, well, anyone and that Darko dude that we never want to talk about again. For our money, Kimbo Slice is the biggest bust in the history of American sports. Think about it. Wasn't this guy supposed to be the face of MMA at one time? So much for that. After getting pounded on repeatedly in the UFC (pause), he was given his walking papers in 2010. Now, he's planning on making a comeback by taking his talents to Japan in early February to participate in a pro wrestling tournament. Knock yourself out, buddy. Just don't expect us to be watching.
