Usyk is looking to retire pretty much once he's took 2 Fury paydays win lose or draw. He will do whatever allows him to maximize his pay so he should. Fury would be wise to sack off Bob Arum because unless he intends to keep fighting which he may then he's wasting money on that old sack.
Usyk should not fight Dubious It makes 0 sense. Never mind the slim chance of losing it's the wear and tear involved.
very little they are all basically "managers" anyway however this gives the Saudis more "control" over the promotion which they get anyway...
I honestly don't think the fight is going to happen one way or the other. Fury is clearly shot and doesn't want to train. He will keep picking low fruit until they strip him. They will probably giftwrap the title back to Wilder--who at least will fight Usyk--so we will get Uysk-Wilder for undisputed when both men are hovering around 39-41.
