LOS ANGELES (AP) — Although Demetrious Johnson’s reign as the UFC’s flyweight champion is approaching historic lengths, he gets only a fraction of the attention lavished on the world’s other top mixed martial artists. The 5-foot-3, 125-pounder realizes that’s partly because he’s only a fraction of their size. The technical brilliance of the champion known as Mighty Mouse has been too much for every contender during eight consecutive wins and a three-year title reign.
