Personally, I really rate him hth, only Joe before him stood a chance. A beaautiful, composed boxer in his prime with rhat devastating power and incredibly brutal jab. Today with modern nutrition he would weigh 235-40. And that is big enough. Tell me why I am wrong.
You're not right or wrong. But at 240 pounds he's not Sonny Liston anymore, kind of like a 205 pound Rocky Marciano isn't Rocky Marciano anymore.
He might be bigger today but seeing Usyk dominate weighing 220 lbs or so, i see no reason why he would need to bulk. I think 220 lbs would be fine for Liston. He was special. Special guy.
Look at it like this, if there's no Cassius Marcellus Clay Jr. Who beats Liston until Joe Frazier was ready in about 1968-1969? And the reason that may have happened would've been because Liston may have been in his forties and winding down. Watching Liston fight at his best is like watching Micheal Jordan at his best. He could do almost anything he wanted to do against most heavyweights in history. Technically sound, and may have been the strongest heavyweight in history( According to George Foreman, who is typically seen as histories strongest Heavy, Liston was the only heavyweight that consistently backed him up when they sparred) That in itself speaks volumes of Liston's physicality. Liston's only fault was coming along when the most uniquely talented, and greatest heavyweight in history was on the horizon. Cassius M. Clay Jr........ Ali.......
