And obviously it has something to do when he loses his fight against the legendary Manny Pacman Pacquiao and then he trash-talks him and in the fight, he can't back all his talking. He made a comeback to beat Barrios, but If I'm not mistaken, Barrios is now a world champion. And this could be another reason why this fight shouldn't be in the PPV as it might not sell.
The fight lacks the hype, Thurman is not a thrash talker and neither is Stanionis, but this is a fairly even fight with Thurman with a very slight advantage, both fighters possess good records even if they do not create big hype in the media, and this is still going to be a great fight in the making, Thurman has proven himself but Stanionis even though a dark horse can pull out a huge upset.
Stanionis is far better than Barrios so Thurman should not take Stanionis lightly or he will be in big trouble.
I think Thurman is a trash talker, remember that he used to be a boxing analyst as well, so he knows how and when to open his mouth. The problem is that Stanionis will not bite on that kind of promotions. And yes, there's no hype even though there is already a schedule fight between the two and the date is near but there is no social media coverage whatsoever.
And for me Thurman is done with boxing, I don't think that he still has the same fire in his belly, if he still has then he should have been fighting and not going on another long hiatus. Money fights for him is supposedly, Spence and Crawford, but it didn't materialized. He could be set for life though when he fought Manny and got a huge pay check in return even though he lost that fight.
