AJ will not need the assist of the judges against Usyk. AJ is an animal, he will destroy Usyk with a vicious KO. Usyk probably will return to cruiserweight or retire after getting KOed by AJ.
I must admit, I always find it hilarious watching Americans talk about this kind of thing when they have the most rotten, corrupted, system on earth. Fix your own corruption. As for the OP question, I don't know. Would AJ get a fair crack if he fought Usyk in Kiev? Do home fighters always have an unfair advantage when it comes to judges, referees etc...? Did Fury get a fair shot when they called the first Wilder fight a draw? Did GGG get impartiality when he fought Canelo the first time?
