He looks super fluid and skilled for his age, skill wise he can do it.. It seems he's only 6'2 max however, not the 6'4 he's billed at. Maybe even shorter!
Without being pithy, yes... if he's better than David Haye. If he isn't, then he's Derek Chisora... or David Haye. Not Evander Holyfield. But being Evander Holyfield, or Usyk, might not be enough these days.
Well in fairness, most of the heavies are probably a little shorter than they are billed at. I think he is big enough that size won't stop him being competitive. Though my position about how much height and weight factor in at the top level is a bit of a minority opinion on here.
He boxes like a tall guy is the problem for me. Could just be working on his fundamentals but I have concerns. I just have to keep in mind that if all goes well he will be the star of the 2030s, he's got some time to develop.
