He only has one defense. It's not a bad thing for him to stay at his division for a minute. Too many champs and even guys who aren't champs yet are talking about two divisions now without even being established as a great in their own divison. What if a fighter wins one title, wins another, then goes on a skid? Was he ever the greatest or was it a lucky break? Many guys could be champ and many guys could be two division champs if they're just thrown title shots without being an established highly ranked fighter. It's a number's game. Doesn't mean they wouldn't drop the ball immediately after though.
