^^^ depends a lot ... How exp is the other guy( Ronnie coleman) ... I know awesome street brawlers u would think they hAve done boxing or something but they just fight for the fvck of it ... In the weekends and stuff ... If that person happens to be 275lb bb he will have a good chance at getting the other one... Also being a martial artist doesn't make u excempt from being hit( u never said so)and being a martial artist u HAVE to have trained to fight a huge guy to beat him down, otherwise u only have technique vs impressive strength and size...if there is a weight difference of more than 100 lbs the chances of the martial artist winning are a lot lower unless he has trained to beAt huge people
