TS%
True Shooting Percentage
PTS / (2 × (FGA + 0.44 × FTA))
One number that captures every way you score: 2-pointers, 3-pointers, and free throws. Regular FG% rewards a player who only shoots layups; TS% sees through that by giving extra credit for 3s and free throws while penalizing volume without efficiency.
This is the metric that pro and college front offices use first when grading a scorer.
What to tag for accurate numbers
- Every 2PT Make and 2PT Miss
- Every 3PT Make and 3PT Miss
- Every FT Make and FT Miss
If you only tag makes, TS% will look perfect (100%) but won't reflect reality.
eFG%
Effective Field Goal %
(FGM + 0.5 × 3PM) / FGA
Regular FG% treats a made 3-pointer the same as a made layup, but a 3 is worth 50% more. eFG% fixes that by giving extra credit for makes from beyond the arc.
It's the single best shooting-efficiency stat that ignores free throws. If your eFG% is up but your TS% is flat, you're shooting better but not getting to the line. If both are up, your offense is humming.
What to tag for accurate numbers
- Every 2PT Make and 2PT Miss
- Every 3PT Make and 3PT Miss
PPP
Points Per Possession
PTS / POSS
How many points your team scores every time you have the ball, pace doesn't lie. A team that scores 80 in 90 possessions is way better than a team that scores 80 in 110.
This is the cleanest team-efficiency metric in basketball. If you only had time for one stat after a game, this would be it.
What to tag for accurate numbers
- Every shot attempt, make AND miss, 2PT, 3PT, FT
- Every Turnover
- Every Offensive Rebound (use the OREB toggle on rebounds)
Possession count is sensitive. Even five missed turnover tags can swing your PPP from 0.95 to 1.10.
POSS
Possessions
FGA + 0.44 × FTA + TO − OREB
The total number of times your team had the ball during the game. It's the denominator that makes every other rate stat meaningful.
The 0.44 coefficient on free throws is a battle-tested empirical estimate, not every FT trip ends a possession (and-1s, technicals, multi-shot fouls), so the math accounts for the fraction that does.
Offensive rebounds extend the same possession instead of starting a new one, which is why we subtract them.
What to tag for accurate numbers
- Every shot attempt (makes + misses)
- Every Turnover
- Every Free Throw (make and miss)
- Every Offensive Rebound, toggle the OREB flag on rebound tags
A/T
Assist / Turnover Ratio
AST / TO
Are you creating more good shots than you give away? A simple ratio that coaches recognize instantly. Above 2.0 means you set up two teammate baskets for every turnover, the floor of "we take care of the ball."
What to tag for accurate numbers
- Every Assist (the pass that directly leads to a made shot)
- Every Turnover
FT%
Free Throw Percentage
FT Makes / FT Attempts
The simplest one. What percentage of your free throws you make.
Why it matters at the team level: a team that shoots 80% from the line is a different end-of-game animal than a team that shoots 60%. End-of-game fouling strategies, 1-and-1 conversions, and clock management all key off this number.
What to tag for accurate numbers
- Every FT Make
- Every FT Miss
FTR
Free Throw Rate
FTA / FGA
How often your offense gets to the line. A high FTR means you're attacking, drawing contact, and putting the defense in foul trouble, even if your shooting % is mediocre, free throws are the most efficient shot in basketball.
This is one of Dean Oliver's Four Factors of basketball success.
What to tag for accurate numbers
- Every shot attempt (FGA)
- Every Free Throw attempt (FT Make + FT Miss)
3PAr
Three-Point Rate
3PA / FGA
What share of your shot diet is from beyond the arc. Useful as a reality check: are you taking advantage of an open look from three, or settling instead of attacking inside?
There's no "right" number, it depends on your roster. But seeing it spike or crash session-over-session tells you something changed in your shot selection.
What to tag for accurate numbers
- Every 2PT and 3PT shot attempt (makes + misses)
TOV%
Turnover Rate
TO / POSS × 100
What percent of your possessions end in a turnover. Way more meaningful than a raw turnover count, because it adjusts for how fast you played. 12 turnovers in 60 possessions is a problem; 12 in 100 is normal.
Another Four Factors stat.
What to tag for accurate numbers
- Every Turnover
- Plus everything that makes POSS accurate (shots, FTs, OREBs)
AST%
Assist Ratio
AST / (FGA + 0.44 × FTA + AST + TO)
What share of your possessions end in an assist. A high number means heavy ball movement and shared offense; a low number leans on isolation and individual creation.
Useful for evaluating whether your team is playing the kind of offense you're coaching.
What to tag for accurate numbers
- Every Assist
- Every shot attempt + Free Throw + Turnover (for possessions)
OREB%
Offensive Rebound %
OREB / (FGA − FGM)
Of every shot you missed, what percent did your team grab back. Raw OREB count rewards bad shooting (more misses = more chances). OREB% normalizes for that, it tells you how aggressively you're crashing the glass.
This is one of Dean Oliver's Four Factors of basketball, alongside eFG%, TOV%, and FTR. Coaches at every level chart it because second-chance points are usually the difference in close games.
What to tag for accurate numbers
- Every shot Make and Miss (so we know how many misses there were)
- Every Offensive Rebound (use the OREB toggle on the rebound tag)
If you don't track opponent defensive rebounds, this estimates opp DREB from your missed shots minus your OREBs, accurate within ~2% in normal play.
HUS
Hustle Composite
OREB + STL + Deflections + BLK
One number that rolls up the effort plays, offensive boards, steals, deflections, and blocks. The plays that don't show up in points but win games at the margins.
Coaches at every level use some version of this: "did you out-effort the other team?" This is the simplest way to answer that.
What to tag for accurate numbers
- Every rebound (with the OREB toggle when applicable)
- Every Steal, Block, and Deflection
