STYLE SUMMARY_
DATA: STALE
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with no dominant single weapon — 83% of wins are by sub.

KEY STRENGTHS

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

KEY RISKS

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