I hate to break this to you guys , but kimbo's been at legends gym for quite some time now , well about 2 years now. And for the people that dont know what that is , thats the gym Bas Rutten runs , and bas is his head coach. Not to mention Big john and randy are good friends with bas and help alot in that gym. So hes already has the same amt of training as someone like Brock. So technically there both in the same boat as far as learning, tho there learning ability and there base is quite different. Being around people like that , for sure u pick up alot of things and of course learn basic grappling and shit like that. I dont care for the guy , but i can assure you he's not your average street bum, not sure if he can withstand the higher tier in the hw division , but im pretty sure hes as well versed as some people in TUF. Cause mainly tuf people nowadays are more for show and many of them arent in established gyms.
