It still happens after Fury V Usyk. Look at Kahn V Brook tonight. That'll do massively numbers on PPV. People over here love an all British grudge match. Obviously it's not as big as the fight could have been if it happened last summer but it'll still break records in the UK.
AJ never recovered mentally from a blow to the ear given to him by Andy Ruiz Jr. AJ had a perfect career until that moment, and from that moment the story changes completely. The defeat by Oleksandr Usyk mentally ended him. The mentality of a true champion would be reflected in an attempt to regain the belt on the other side (against Tyson Fury).
