Ball security
What it measures
It is turnovers per 100 touches, and lower is better. From there it becomes a percentile, and then a grade.
Measured per touch rather than as TOV%, because TOV% puts players who barely handle the ball at the top
Terms used here: Touches / TOV% (turnover ratio)
How many players are ranked
This metric has an attempts cutoff. Players short of it are shown as “—” and are not ranked — which means there were too few attempts to rank them, not that they are bad at it.

Other metrics in “On-ball”
- Playmaking — AST% (how many of the team's baskets you had a hand in)
- Half-court creation — Synergy's pick-and-roll ball handler plus isolation: how much a player is trusted to create in the half court, and how well those plays end. Drives off a closeout are classed as spot-ups by Synergy, so they are not counted here
- Driving — Attacks at the rim: how often (per 100 possessions), the points each one produced, and the free throws each one drew, combined in equal parts
