Technically from what I've seen he's rather good, he didn't invent hot water but good on stand up and on the ground, and in between, no particular flaw. Except again he's been mostly dealing with opponents smaller than him If you look in this video it's clear, while they are all big names, or rather "former" big names (they aren't in their prime anymore), they are all smaller https://www.youtube.com/watch?v=ebeQBYvWKsw Example https://en.wikipedia.org/wiki/Quinton_Jackson Height 6 ft 1 in (185 cm) Weight 265 lb (120 kg; 18 st 13 lb) June 20, 1978 (age **42**) Even quinton jackson who's heavier, is much smaller and much older (and much fatter) See what he did here? https://youtu.be/ebeQBYvWKsw?t=172 Rushing on a hook and taking it in the skull instead of the chin in order to close the distance? Ok it works... But that's typically the type of stunt that might turn fatal against a brock lesnar type for instance
