Reality is he hasn't been working on much at all since turning pro, he's the exact same fighter we saw in Rio. He has a style that prioritizes landing the rear hand as that's the punch that amateur judges seem to favour when scoring amateur fights. It's probably why he doesn't have much of a jab as why bother when judges will take landing one rear hand over a bunch of jabs. Hopefully after the loss to Dubois and with a new trainer he learns to add some more tools to his game. But he's wasted most of his pro career which is a shame.
That's what I thought, he looked just like the fighter Dubois pummeled into a bloody mess,,as for Joyce? A more dangerous heavyweight will really hurt him
