WELL ROUNDED

KEY STRENGTHS

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

KEY RISKS

Volume strikers have outpointed across full fights — output drops after R2.

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 103 rated fighters on the UFC bantamweight roster (anyone with a UFC bout in the last two years or one booked).
