if he's been shafted as much as they say he has, he's gotta take most the blame. Yes, Promoters do this, Managers do that , but ultimately , he's a fucking grown up man being. nobody holds a gun to his head to sign the contract.
you'll get plums like @Master get all indignant about it , saying it's wrong that the fighter got shafted, then he'll spout off about Mayweather. so he's not happy when a fighter earns shit money and he's not happy when a fighter earns good money!
he shouldn't have been so fucking stupid basically.
