Since MMA's inception, the general concept of family has been an integral part of a sport that is often billed as individualistic.
Now more than ever the sport has seen family competition, with fathers training sons, brothers fighting on the same cards, and overall family camaraderie on high display.
The Gracie family popularized the idea of one style being better than another, with numerous fighters and families have tried to disprove the Gracie theory, with not very many proving successful.
Take Royce Gracie for example at UFC 1. After his impressive wins over Art Jimmerson, Ken Shamrock, and Gerard Gordeau, Gracie realized his family's true purpose: proving his family's style was the best in the world. Surely a better feeling than any belt or dollar can give a fighter.
Flash forward to UFC 128 in New Jersey. Dan and Jim Miller of Sparta, N.J., fight in front of their hometown crowd at the Prudential Center. Though Dan lost and Jim won, nothing will take away the experience the brothers had that night.
And so, brotherly love has been redefined in and outside of the octagon. However, one question remaining is which brotherly duo is the best MMA has to offer?
