he beat a tattoo in Tank. Tank is the biggest loser in MMA history. Worlds most famous fighter with a losing record. not that i would challenge him in a street fight. i'm not stupid....
but as for kimbo he's been training under bas rutten and several other MMA legends, combined with his natural toughness and obvious power... the only thing that falls into question is his ground game and keeping form. infinte times in MMA have bigger stronger tougher guys been beaten by more technically sound figheters. which tank is well.. not. kimbo needs to make the shift from sideshow to legit leagues and fights though. tank abbot is 42 years old. its not impressive to beat a 42 year old former bouncer from the dark ages of MMA who hasn't won two fights in a row since 1998. Kimbo's got the ahtletic ability that goes without saying and he looked to be in teh shape of his life, but i think kimbo is like 31.. so he might be hopping on the mma train too late to become a real force, as for who can beat him? i'd say the majority of the up coming MMA heavyweight class (Ben Rothwell anyone?) .. UFCs heavyweights are 95% over the hill.
