No. He landed everything including the kitchen sink on a very green Joyce, but didn't drop him. This content is protected
he didn't and even if he did it means nothing, Calzaghe lost as an amateur it meant nothing in the pros, Lomachenko may be the best amateur and he got beat by a gobby Naseem Hamed clone as a pro
I didn`t watch it all, but Dubois doesn`t have Usyk`s offensive skillset so he won`t land as much, Joyce is a good finisher so will probably destroy the green Dubois, we`ll see, Usyk did completely out-box Joyce though.
