Fedor and his managment can not be seperated, he picked them to represent him.
This. Fedor seems like a nice guy. But he chooses people to represent him. So no, it isn't "oh bad manager" "Oh Fedor is a saint". He chose those men to handle his business and represent what he wants.
He either agrees with their negotiating and ways of business. Or he is not his own man and is a puppet for rich folks. Either way Fedor damaged his own reputation by being associated with those guys and taking crap fights.
Mousasi seemed to figure out that life in the UFC is a much better path than some irrelevant events in Russia. Fedor is either dumb as a rock, a twat like his representation, or a scared little man who is loyal to guys who do him wrong.
