I've been asking myself the same question, like why are exhibition matches so hyped these days? People already know that the fight is somehow scripted but they still want to pay good money to watch the fight in person or live in their respective homes.
Maybe because the people have missed seeing the good veteran fighters fighting again that once built their names in their primes or maybe there is another reason why but yes, exhibition fights are also a good way to get good money these days as long as you're popular.
It's because of the involved people and the ones organizing it. We all knew from the Jake and Logan Paul brothers that they were the ones who have made such fights.
Like they're having a match against a veteran and retired UFC fighters to box. That's even odd that they're not playing the sports that these veterans have been once become a pro.
