He's a 1-d, kind of 2-d fighter. He has great BJJ, pretty good striking. But he has nothing in the transitions between them (wrestling, scrambling, judo, whatever you want to call it). His style is not dynamic; he's good at most distances, but he's not good between distances -- he doesn't blend distances. His skillset is a collection of many individual martial arts rather than mixed martial arts. The classic muay thai + BJJ trap that led to them getting replaced by wrestle boxers. That will prevent him from ever winning at the top level that Tony is at.
