Joshua doesnt have a glass chin but he took it on the cheek not the chin. Pulev for instance took a right hans from klitschko bang on The chin but didnt go down on tgat one despite numerous of heavy blows and kd's prior to that. Joshua has a good chin.
Neither are a valid comparison in reference to Ruiz - the McDermott fight was 11 years ago when Fury was very green - AJ was in his prime vs Ruiz. He beat Wallin reasonably comprehensively despite the cut. I think it would be a good idea for Fury to 'right that wrong' but I suspect he may only have 3 fights left. Wilder and AJx2 or AJx2 then Usyk.
They have done so in past attempted to make the fight e.g the 40% offer for after the first Fury and Wilder fight. Although Hearn isnt popular, the offers he states he makes dont tend to be disputes by opposing promoters and they normally confirm they have either confirmed talks ongoing or have received the offers. With Arum promotinng of Fury than Warren I am much more confident that the fight will be made as he is a similar to Hearn in the aspect unlike PBC who are just all hot air as proven with Wilder, Ruiz, Ortiz and Sp3nce coming up excuses not to make the big fights.
Hmm, I think that's moving the goalposts a bit from what you originally said. I think with Fury, the 50/50 thing is mostly ego. We also don't know the other terms of the 40% offer, it might have been heavily weighted towards Joshua whilst they had the stronger hand. Agree RE: Arum. I just hope Wilder doesn't get in the way.
