yea my glass chin of mma in this present time go something like this 1) bigfoot 2) arlovski 3) cro cop 4) wandy This is in no particular order and i believe these guy had good chins back in the days however time has caught up with them and bigfoot is like the wladimir klitschko "suspect chin" of mma, no discrediting any of the legends. Bigfoot sucks.
Money. These guys have nothing but their names left, but that can still earn them decent money on some of the smaller promotions.
