Never saw this before, KUDOS! Joe looked like a Middleweight. Buster was always an x-factor to me after turning pro. (having male tits doesn't necessarily mean you're out of shape: See Jimmy Young). Buster could box and had a bit of a whalop. Both hands but a couple of those left hooks were precise! Perhaps he just lost his moxie/desire after turning pro, comments appreciated. I'm going to go back and look at his pro career and see where the 'downslide' happened. He did have boxing tools!
Frazier sure as hell got revenge though lol Mathis surprisingly doesn't look that bad for 300lbs, looks kind of like the 255 Holmes that fought butterbean
