"I’m not aware of any professional athlete union that did not improve the working conditions and increase the paychecks of its members. I believe it will come someday in MMA, not because things are bad right now but because it’s just part of the normal evolution of all major sports. I’m not a "politician" and people know that I’m not a confrontational person or someone who likes to be in front, so it would be hard for me to lead that kind of initiative. But I will never be against something that is good for the fighters."
