His skills are limited but he does have a big punch. His punch in my opinion is greater than Joshua. He was able to knock down Dominic Breazeale with one grazing punch while it took Joshua who is taller, more skilled ( which isn't saying much) and landed far more power punches longer to do so.
No cause he doesn't have the stamina, energy to bang like he needs to. He's another gasser. He only drew on the cards with Gerald Washington cause GW gassed more than he did. He hasn't even fought a 12 round fight yet. I don't think he hits as hard as AJ either.
