Then I suspect that Wilder will attempt to negotiate the AJ fight. I feel that the threat of loosing the life changing payday that he gets against AJ will likely be the reason that Haymon and Wilder will no longer waste anymore time.
A fourth fight becomes highly interesting. Joshua sure as hell won't fight either of them, so they might as well fight a fourth time.
Wilder is done for. He cant learn boxing fundamentals in 6 months. Any plan set by his staff to beat Fury will fail.
Then Wilder replaces Fury in the AJ matchup negotiations. Wilder will certainly want his part from the massive staging offer Saudi Arabia has made for the undisputed HW fight. I dont believe there will be a fourth fight with Fury.
