Simon was a big, imposing looking guy but he looks like utter shite on film. He seems not to possess a single fast twitch fiber in his entire body. He is an arm-puncher with bad balance. He rarely gets good leverage on his punches. He is a specimen they tried to convert to a boxer. No offense to the man but he doesn't look class in the ring.
More interesting the 256 lbs Simon couldn't beat the 186.5 pounds Turkey Thompson. Big difference between the bone structure and muscular power Simon was just a featherfist.
