WELL ROUNDED

Well rounded fighter with no dominant single weapon — 44% of wins are by sub.

// HOW_WIN

Drags it to the mat and hunts the finish — submission threat opens up off transitions.

// VULNERABILITY

Pressure boxers willing to wade into the pocket have found chins on offer; cardio drops in late rounds.
