first Manny has a very Discipline boxing career and His reputation being senator is a type of serious person not like when MayWeather and Conor face that is a Joke and Money matter only no professionalism involved.
Everything has a price, we are talking of a big amount of money here and I don't think Manny's camp would not think twice before making a decision.
Regarding your statement, do you have an article you can share that Manny's camp won't allow this to happen?
We cant be sure if Manny's team wont accept if the price or offer is good.His reputation wont really be hurt up but its clear as water on whose gonna win
thats why this fight would be just good for entertainment not for an actual boxing fight essence.
