Liston either wins by stoppage or points. Gassievs chin may get him the distance but he'd take a beating off that jab.
Always thought Gassiev was underrated, especially on classic (and particularly after the loss to Usyk), but he doesn't win this. He's just too out-gunned in almost every aspect.
I think Gassiev might be the hardest puncher Liston has ever faced but the reverse could be true. Neither seem especially difficult to hit.
Gassiev looks like a talent despite the bad loss to Usyk however he's done nothing to suggest he would be able to handle Liston.
Gassiev doesn't use his height and reach and fights like the shorter fighter even when he isn't and that's recipe for disaster against Liston, Liston would control the range, pick him apart and KO him
