A lot of people think it's a conspiracy theory that 'brand' fighters are protected from being busted. In fact it occurs in all sport. It can be hard to get hard proof, because obviously this is hidden. But if you believe it's just speculation that this type of corruption exists, here is a proven example in tennis. Agassi admitted after retiring that he was busted for rec drugs, speed or some such, and they covered it up. The reason is that he was a huge money spinner for the tournaments and his sponsors. It's that simple. They broke the rules to protect their profits. Obviously a brand like AJ ticks all the boxes for getting protection. Problem in this case is they also take long breaks because they're pure opportunists and are likely waiting for Usyk to beat Dubious so they can try to rob him again at Wembley. Dubious is harder to rob as they found out. Hearn is also smarter than Fury's imbecile team and wouldn't put his brand in a fight after concussive damage only months before, something that possibly lost Fury a unified champ status.
After the KO beating from Dubious, it makes sense to have a year lay off to recover. Too many boxers end up punch drunk by returning too quickly from ko losses.
