Kimbo is huge in boxing too. We have some pro boxers that come in our gym from time to time and they all know KIMBO and part of thier locker room talk is how to fuck him up with a good stiff jab. Believe this, those guys would expose Kimbo.
I will say this though, when he was announced at the Elite XC event, you would have thought they just announced ELVIS. Gary Shaw made a great move here! Its already payig off for him.
