I think your forgetting Marciano's 88 % KO ratio ...and that's against HWs. Judges won't be needed here.
I have the rock by knockout If he is on the same 'supplements' as today's guys? He would be an absolute monster weighing well in excess of 200lb Also canelo looks very short. I don't think he is even the 5'8
Some clown said he only beat men smaller than him. I threw facts at him and he just kept trolling. Ignored him. Marciano fought 17 fights against opponents who outweighed him by 10 or more. More than a third of his fights were against bigger men. I didn’t even add all the men who had 1-9 pound advantages, which were common.
