The share of a team's offensive possessions that begin in transition, right after a stop or a turnover, before the defense has set.
Transition is the most efficient offense there is. With defenders scrambling back, the offense has an edge in numbers or matchup, and the shots are easy. Transition Frequency measures how often a team gets to play that way. A high figure means a team either forces turnovers and runs, or pushes the ball the moment it has it. It is a window into identity: run-and-chaos teams against patient half-court ones.
TRANS% = Transition Possessions ÷ Total Offensive Possessions × 100
A transition possession usually means one that starts within a set number of seconds of a change of possession, before the defense is organised. The exact cutoff varies by data provider.
Trans%: Transition Frequency / Trans_Poss: Transition Possessions / Total_Poss: Total Possessions
A team that pushes pace creates transition chances for both sides. Run constantly and you are also more open to the other team's break when your own attack breaks down. Transition without the discipline to stop the opponent's is as much a liability as a weapon.
Providers draw the line differently. Some count any possession within five seconds of a change, some within eight, some use tracking to judge whether the defense was set. Figures from different sources are not always measuring the same thing, so they do not always match.
Olympiacos in 2025–26 ran off their defense. The league's best defensive rating (109.3) meant a steady supply of forced misses and turnovers to push the other way, and it fed a league-best +10.8 net rating and a 30-12 record. Speed on its own does not do this: Paris played faster than anyone (80.2 possessions a game) and finished 15-23, because a team that runs constantly also exposes itself to the other team running back. Transition works best when the defense is what creates it.
Transition frequency is the share of a team's possessions that come in transition, before the defense is set, rather than in the half court. It describes how much a team pushes the pace.
Count the possessions that start as fast breaks or early offense and divide by total possessions. A high share means a team that runs at every chance.
Transition possessions are far more efficient than half-court ones, because the defense has not organized. Teams that generate more of them get easier points, so how often a team runs is a real edge.
