Kimbo has only faught Ray Mercer. Thats the only professional fighter he has faught. Kimbo be beating down street cats. As for endurance he ran outta gas against Gannon. Tank been fighting in the ring. That foo KO's foos that fight for a living.
Not that Kimbo isn't a tough guy, but I still don't think he has proven himself in MMA. With that being said he would more then likely beat Tank down these days. Tank in his prime would smash the hell out of Kimbo though, I have no doubt about that.
