STYLE SUMMARY_
DATA: COLD
FIGHTING STYLE
WELL ROUNDED

Well rounded fighter with no dominant single weapon — 37% of wins are by dec.

KEY STRENGTHS

Banks rounds on the scorecard — pace and positioning over splash damage.

KEY RISKS

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