He prioritizes defense and survival above all else. Jiu-Jitsu philosophy. Probably the only guy to truly apply it in the modern era of MMA.
Another way of looking at it is to say that if he hadn't finished any of his fights and they'd all gone to decisions that he lost, would you think that his opponents had done anything beyond winning a points game? They certainly haven't been in there hurting/dominating him or doing any significant damage. He keeps himself safe at all times and waits for his opportunity to finish. That's the single best way to fight if you value efficiency and longevity in the sport. No one (so far) can finish him, but he can finish all of them. It's amazing that he's so confident in his approach that he's willing to give up rounds he's capable of winning, because it would compromise his defense and finishing prowess.
