There's no disputing that Ultimate Fighting Championship (UFC) Featherweight king Conor McGregor is the most closely watched combat sports star in the world today.
His ability to stand out among his peers, create unfathomable fan interest, and fill the rumor mill is like anything we've ever seen at the mixed martial arts (MMA) level. In turn, many people try to attach themselves to McGregor's name in order to promote their own.
Most recently, Brazilian Jiu-Jitsu legend Rigan Machado threw out the idea that actor Ashton Kutcher, who is a purple belt under Machado, could out-grapple the 145-pound king.
