STYLE SUMMARY_
DATA: COLD
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with no dominant single weapon — 43% 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.

WHO THEY
ACTUALLY FOUGHT

A record says how often a fighter won, not against whom. These ratings weigh every result by the opponent's strength at the time, then compare this fighter with the 60 rated fighters on the UFC flyweight roster (anyone with a UFC bout in the last two years or one booked).
