For example, if Joshua beats Whyte can he say to Eddie Hearn "get me this guy next" or is it a case of the promoter saying "No, you're fighting this guy and that's it."
It's all negotiable, a boxer can tell his promoter to f off if he really wants but then how would long would he have that promoter? And, if a promoter lets him go because he won't make any decent fights then he is gonna have tough time being promoted at all.
He can say "get me this guy" but the fight may be unmakeable. The other opponent may have a fight lined up, may be on another network, may have a different view about where hes going in his career, the money may not be right etc etc etc I think a lot of fans overlook how much goes into making a fight. 2 guys may want to fight, but thats only about 10% of what is needed to get a fight done
It depends. Prospects like Joshua have a team to make matchmaking decisions, but elite fighters like Floyd or Andre Ward have a lot of say in who they fight. That said even top fighters usually have a team they confer with before making big decisions. I remember Cus D'Amato wouldn't let Patterson fight Liston, since he thought Liston was all wrong for him. Patterson fired him and fought Liston anyway and was destroyed twice. Sometimes a good manager or team members can see things that a fighter can't or might even refuse see.
Boxers always choose Who to fight, nobody forces them into the ring. They get options, promoters are always in contact with each other making match ups for there bills, and if a boxer wants a specific fight there promoter will try for it if it's a realistic match that makes sense, plus boxing organisations are choosing who fights for there belts aswell but it's up to the fighter if they want to fight or not.
Your not correct. A fighter provided he has a manager decides the best fights based primarily on how much the fight is worth financially and if his boxer won't get hurt. Fights are offered by match-makers who work for promoters in making the fight bill. The manager deals with the match-maker to decide the financial side, number of rounds. At a higher level option agreements may take place. Only the very elite (less than 1%) will dictate who they will/wont fight, but boxers will usually fight anyone, it is just the payment level or option agreements within a contract that stop fights being made. If a boxer has no manager then he manages himself, ascending boxers are rarely unmanaged. Some journeymen might look after themselves if they know enough match makers they would then decide who they fight, they usually have the sense to know who would not hurt them so they can keep their licence.
I think they have more say than were kead on to believe, if the fighter really wants to fight they can make the fight. Most guys are just content with letting there opponent get picked for them.
I should of said a fighters team and promoters, and I agree most fighters will fight anyone and just want to get in the ring and make money and improve there rank.
