Pace and possessions, explained: why per-100 stats matter

A possession is one team's turn with the ball, ending when it scores, misses and gives up the rebound, turns the ball over, or the period ends. Crucially, an offensive rebound continues the same possession rather than starting a new one — the trip only ends when the other team gets the ball. Both teams get almost exactly the same number of possessions in a game, because they alternate.

Pace is an estimate of how many possessions a team uses per 48 minutes — the length of an NBA game. A high-pace team pushes the ball, shoots early and racks up possessions; a low-pace team walks it up, works the clock and uses fewer. Pace is a stylistic fingerprint: two teams can be equally good while playing at completely different speeds, and neither speed is inherently better.

Pace is the reason raw totals mislead. A team scoring 118 a night is not automatically better than one scoring 108 — the first might simply play faster and get more possessions. To compare fairly you divide out the pace: offensive and defensive ratings are points per 100 possessions, not per game. Per-100 stats strip away speed so you are measuring how good a team is with the ball, not just how often it has it.

Pace inflates or deflates everything counted per game — points, rebounds, assists all rise in a track meet and fall in a rock fight. That is why a high total does not always mean great offence, and why the same two defences can produce a 130-125 game or a 95-92 one depending only on tempo. When you see gaudy per-game numbers, always ask how fast the team plays before you are impressed.

Pace also drives matchups and totals. When a run-and-gun team meets a grind-it-out one, the game's speed — and its final point total — often hinges on who imposes their tempo. That is why pace and per-100 efficiency sit at the heart of modern basketball analysis, and why the data-driven previews on SportMetrics weigh tempo alongside efficiency rather than being fooled by raw per-game scoring.
