STYLE SUMMARY_
DATA: COLD
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with no dominant single weapon — 63% of wins are by sub.

KEY STRENGTHS

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

KEY RISKS

Top-position grapplers who can chain transitions force submissions when scrambles open up.
