STYLE SUMMARY_
DATA: COLD
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with elite knockout power — 57% of wins are by ko/tko.

KEY STRENGTHS

Closes distance and trades — most wins come from heavy hands inside the first two rounds.

KEY RISKS

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

WHO THEY
ACTUALLY FOUGHT
