Usyk is more than capable of backing down a HW

[WWWK]

he's not sitting down on his punches and not generating much power.

Agreed. He didn't really commit to his shots vs Chazz. I expect a better level of opponent next time out will force him to.

Usyk will do good at heavyweight. I have always found him frustrating to watch though, I just find his style boring as he just seems overly cautious even at cruiser weight. His style will frustrate the heavyweights though as most of them are flat footed except Fury.
