Sounds like a paternalistic relationship with Haymon being the tenacious, overly intrusive parent.
The thing you should be thinking about is why would any fighter (and those around him) let that happen?
I haven't seen these contracts, nor listened to the negotiations but let's try to put Haymon in the best light possible for a minute. Maybe Haymon has convinced these fighters (and those around the fighter) that if they follow his rules he well guide them to that wonderful place beyond boxing. That place where their money is working for them everyday and their families future's are secure. Oh yeah, dude, heaven on earth…retirement with security and dignity. It's possible. Lol
Haymon could be what a lot of us seem to want him to be, that dark shadow gliding past, just under the surface, of the sea of boxing. That merciless, conscienceless predator (Don Kingish?) who will rend people's lives for the almighty dollar. It's possible. Lol
I think Haymon is somewhere in between. He is always going to make money, he probably will take advantage if you are stupid enough to let him, but I think he will deliver with sound advice, good paydays and he seems to let fighters set their own pace (is that good or bad?), and I don't know if he's good or bad for boxing.
One thing I'm sure of is that every contract is not the same! He might have a standard contract, but almost every clause will be negotiable and anyone who would sign a contract without an independent review by a boxing contract lawyer is an idiot.
