LOS ANGELES -- Demetrious Johnson has heard the criticism before, and he knows he'll hear it again this week.
The UFC flyweight champion is widely regarded as one of the premiere pound-for-pound mixed martial artists on the planet, often trailing only UFC light heavyweight champion Jon Jones and longtime UFC featherweight champ Jose Aldo in major polls.
But his pay-per-views and his buyrates haven't matched his success inside the Octagon. And with what many consider a weak UFC 186 card on Saturday night in Montreal headlined by Johnson's title defense against the talented-but-unheralded Kyoji Horiguchi, Johnson has braced himself for the inevitable questions.
