Conor McGregor is an expert at manufacturing rivalries. At the drop of a hat, the man can whip up a compelling grudge match unlike anything ever seen and transform a standard fight into a vicious bloodfeud.
That said, very few have been able to keep step with McGregor for any length of time. Fighters like Dustin Poirier, Cole Miller and Eddie Alvarez have been compelling foils for the Irishman but none were able to enjoy the spotlight for any serious length of time. Meanwhile, potential opponents like Donald Cerrone, Rafael dos Anjos and Jeremy Stephens all made a splash at one point or another, but were unable to actually take a shot at the king.
