I didn't get a chance to see the full clip. But if your question is just about Joshua not attending the fight then I don't think there's anything wrong with that.
Why would he go to the fight, ticket sales are low for the so called best fight in the world. Before the Wilder fans say that he is ducking Wilder,Wilder did not go the previous AJ fights.
It's not certain that Wilder will beat Fury. With that said he should be there if not to call the winner out to get called out and hype the future fight up.
Joshua isnt going because he is a gentlemen. Joshua has a big loud distinctive laugh and watching Wilder is funny he is bound to laugh when Wilder starts windmilling thin air or starts tripping over his own feet and with only 9 people going to in attendance of the fight i think Joshua would be heard, so he is doing the gentlemanly thing and staying away. Does it mean he clearly doesnt want the Wilder fight? Some say yes but seeing as Joshua and Hearn are sending YET MORE contracts to Widler id say that is much stronger proof of whether he wants to fight Americas biggest fraud or not.
Joshua does not need to hype a future fight up, we have seen what he can generate, the fight with Wilder will sell out, thats being either in the UK or the States.
