I’ve never boxed but I have a few years of Jiu Jitsu and even more of wrestling. A couch potato wouldn’t beat a trained fighter, but a 250 pound man of stocky build, medium talent and maybe two or three years of training probably couldn’t be knocked out by any 100 pound man in the world, and would probably win if he were lucky enough to land a good punch.
