How do you know what kind of contracts fighters sign? Keith Thurman may have had his reasons to reject Roc Nation, though it is a lot of money.
And why should a fighter care more about the sport than his health and money? It's not like they are in the NFL, NBA or MLB, where it's all under one association. Everyone is on their own in boxing, with several promoters. It's not up to the fighters to keep the sport popular. I'm sure they're main focus is to make money and put food on the table for their family, not keep the sport popular.
Haymon fighters of this generation solely look for the path to greatness with the least resistance which is why fighters of yesteryear are held to such a higher regard because they fought "Whoever, whenever, wherever, however " and didn't use the negotiating table as a tactic to squander potentially GREAT fights.
Can you imagine if SRR turned down a fight with Jake Lamotta because Jake didn't sell enough tickets at the gate in his previous fight before their first encounter?
The point is too many fighters want to be labled great but don't want to take the hard road to greatness by fighting the best at their best no questions asked. Instead, it's about preserving their "0" while collecting the most money possible short changing fans in the process, not to mentioning destroying the sport.
It's their health they put on the line every time they step in the ring, so for you to criticize as a fan for signing with Al Haymon or any business decisions they feel are best for them, is pretty damn retarded. Like I said, I understand as a fan we get frustrated. But this isn't a fuckin tennis match, it's boxing where in one punch their health can change.
