kimbo's a circus act and chuck seems to be on the way out (which sucks because i was a big fan of the guy). the thing is, chuck has almost nothing to gain from it. if he wins, hooray. he beat a guy that got knocked out by a scrub in a basement and hasn't fought anyone really remarkable. if he loses, his career is doneski.
kimbo exists for one simple reason: he's a big scary black dude. if those videos were the exact same, with every fight ending exactly as it did, but kimbo was a dumpy looking white guy named brandon, he would still be fighting for rent money in miami.
