STYLE SUMMARY_
DATA: LOW SAMPLE
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with no dominant single weapon.

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.
