Our read — not official stats. Six 0–100 scores, each a percentile rank against the fighter’s own weight class (the full roster where a division is too thin to rank in). The better score on each row is highlighted in that fighter's corner colour.

Significant strikes only, as recorded by UFCStats, across the fighter's whole UFC career. Shares are raw counts — nothing here is modelled or smoothed. Accuracy is landed ÷ attempted and comes from the per-round tape, which covers slightly fewer fights than the totals do. “Field” is the average fighter in that weight class, or across every division where a class is too small to average.
Career UFC takedown rates. Red corner left, blue corner right.

Career UFC takedown rates exactly as UFCStats publishes them: takedowns landed per 15 minutes, completion rate, submission attempts per 15 minutes, and the share of takedowns tried on them that they stuffed. Attempts per 15 is the one derived figure — landed ÷ completion rate — and it is omitted wherever either input is missing. UFCStats writes 0% where no attempt was recorded at all, so a percentage of exactly zero reads “n/a” here rather than as a measured rate. “Field” is the average fighter in that weight class, or across every division where a class is too small to average. Rate bars run to the population’s 95th percentile (6.09 takedowns / 15m); a fighter above it pins the bar. Percentages are drawn on their own axis.
