Almost every aspiring or up and coming fighter I know has the goal of making it to the UFC. Then there are some who understand the logistics of making money in the fight game.
Some fighters are smart enough to realize that they will be fighting for peanuts until they make a name for themselves and aren’t willing to take a pay cut from being a regional star for the chance that they might make it big. On the other hand most think that the UFC is all about getting exposure because the UFC is the biggest platform and in the even they make it they will make more money in the long run.
The thing is that when you sign a UFC contract you are accepting those terms hoping you will eventually make those big bucks and agreeing to their terms. Nobody forces you to agree, you agree because you want to fight in the UFC, you could go elsewhere but choose not to. So when someone like Francis who now wants to make even more money than he agreed was acceptable under the terms with the UFC it makes no sense.
