It’s defintely not going to be Usyk. The two greatest modern day CW to HW champions in Holyfield and Haye, both faced below top 20 opponents in their first fights at HW. You can’t put on all that weight and go straight to a championship fight. It’s already agreed to be Whyte is it? Unless he loses to Chisora..then it could possibly be Ortiz or Miller.
I just think they need a big name to market AJ as the number 1 if Wilder and Fury fight again although the WBC sanctioning a fight or ordering a fight are two different things
