Smartest gamble is Wilder. Parker still shows up sometimes, I think a chance to get revenge on AJ would motivate him. Wilder, on the other hand, is all the way done. The fire has gone out, he's gun shy, his chin is cracked, and AJ would have an enormous weight advantage. I don't know if it sells though. You probably need Wilder to win a fight to generate interest and that's a tall order at this point.
Yes, I agree, Wilder is the fight he should make. It would sell, as a novelty, and on the promise of a KO one way or the other. A Joshua-Wilder would not have significance to the world rankings though. I think Parker would beat Joshua. But Parker's generally not a devastating puncher and Joshua has a win over him for years ago, so it is a fight Joshua would have some level of confidence in winning, or at least surviving without being annihilated. And IF he could beat Parker he could legitimately claim a place in rankings again. It is a gamble, and I think he'd lose, but the reward justifies that risk.
Don´t know, the says otherwise, but he seems to have lost his hunger, only fighting for money now. Won´t be beating any of the top guys anymore. He may have a very good rematch option next and still the chance to become 3 x champion. As for other options, Wilder, Parker, Kabayel, Dillian, Baby Miller, Joyce, are all interesting matchups. A win next against any of these names makes the Fury fight atractive again.
Run the parker fight back or fight Wilder, a win against either would begin to generate some momentum for him. Personally though I think he should consider retirement at this point.
Joshua was finished as soon as Dubois catched him and knocked him down for the first time, Joshua's fans and casual boxing fans will desperately say that Joshua can win if he pulls himself together, we heard a similar story before the first fight with Dubois...
