Why do they not make a mandatory defense for Fury against Usyk? Fury cannot reject it and if he does the belts go to Usyk. I think that is the only way we will get this fight to happen because Fury does not want to sign the contract. Usyk is willing to fight for nothing and has pride. Fury is a joke and is not deserving of the belts if he does not want to fight the real challengers instead fight people past their prime.
The 4 major sanctioning bodies (WBA, WBC, IBF, and WBO) cannot include in their rankings the already world champions from the other major organizations. Maybe it can be agreed but it's been years now that these 4 sanctioning bodies tried to negotiate in creating an undisputed champion per division to no avail. An attempt to do that without a pre-approval from the other major sanctioning bodies can only spark a war just like the WBC vs WBO before and it will only stop future unification bouts.
Fury is not only trying to bluff Usyk with heavy demands but it is also trying to disrupt Usyk's training. Usyk is already training for weeks already and there were rumors that Fury is yet to set up his own training camp. Although Fury at times tried to post that he is training but most likely not the usual training when someone has a scheduled fight. And Fury probably needs more time here as I doubt he will come at the same weight when he fought Wilder, Whyte, or Chisora. Fury is a smart guy and he won't come that heavy against a speedster like Usyk. Fury will probably fight when he feels right and ready. He might cut off Usyk's camp as the Ukrainian cannot overtrain and needs to relax his body. And it looks like Fury will make Usyk inactive for a year.
