Yeah or in with some big punchers like Breazeale/Helenius (I would include Price but that may have been done to death already haha.
If Joshua v Wilder gets made for April, then the winner of Whyte v Chisora. If that fight doesn't get made, Usyk is ready for Joshua next up. Joseph Parker is also a good call although if I was the Parker camp, I wouldn't take that fight. Money talks though.
Usyk vs Povetkin on the Joshua-Whyte 2 undercard would be an easy sell, a good work into em fight for Usyk too with little discrepency in weight/height.
I'd enjoy watching him bamboozle Big Baby the OAP terrorising scourge of the super-duper-heavyweight division.
