Formula: Offensive Rating = (Points / Possessions) x 100
Worked example — ORtg: 109.5 | DRtg: 104.9 | Net: +4.7 | Pace Factor: 1.040
Formula
Offensive Rating = (Points / Possessions) x 100
Offensive rating normalizes scoring to a per-100-possession basis by dividing actual points by possessions used and multiplying by 100. Defensive rating does the same for opponent scoring. Net rating is the difference between the two.
Worked Examples
Example 1: Fast-Paced Game Analysis
Problem:Team A scores 115 points on 105 possessions against Team B who scores 108 on 103 possessions. League average pace is 100.
Solution:Game pace = (105 + 103) / 2 = 104.0 Offensive Rating = (115 / 105) x 100 = 109.5 Defensive Rating = (108 / 103) x 100 = 104.9 Net Rating = 109.52 - 104.85 = +4.7 Pace-adjusted team score = (115 / 105) x 100 = 109.5 Pace-adjusted opp score = (108 / 103) x 100 = 104.9 Pace factor = 104.0 / 100 = 1.040 (4% faster than average)
Result:ORtg: 109.5 | DRtg: 104.9 | Net: +4.7 | Pace Factor: 1.040
Example 2: Slow-Paced Defensive Game
Problem:Team A scores 88 points on 85 possessions against Team B who scores 82 on 84 possessions. League pace is 100.
Solution:Game pace = (85 + 84) / 2 = 84.5 Offensive Rating = (88 / 85) x 100 = 103.5 Defensive Rating = (82 / 84) x 100 = 97.6 Net Rating = 103.5 - 97.6 = +5.9 Pace factor = 84.5 / 100 = 0.845 Despite low raw scores, efficiency was strong. At league pace: Team A would score ~103.5, Opp ~97.6
Result:ORtg: 103.5 | DRtg: 97.6 | Net: +5.9 | Better than the fast game despite lower scores
Frequently Asked Questions
What is pace adjustment in basketball analytics?
Pace adjustment is a statistical method used to normalize basketball performance metrics to account for the speed at which teams play. Different teams play at vastly different tempos. A fast-paced team like those coached by Mike D'Antoni might average 105 possessions per game, while a slow-paced team might average 90. Without pace adjustment, comparing raw scoring totals between these teams is misleading because the fast team simply has more opportunities to score. Pace adjustment converts raw statistics to a per-100-possessions basis, creating a level playing field for comparison. The most common pace-adjusted metrics are Offensive Rating (points scored per 100 possessions) and Defensive Rating (points allowed per 100 possessions), which together reveal true team and player efficiency.
How is pace calculated in basketball?
Basketball pace is defined as the number of possessions a team uses per 48 minutes (or per game). The basic formula estimates possessions using box score statistics: Possessions = Field Goal Attempts - Offensive Rebounds + Turnovers + 0.44 x Free Throw Attempts. The 0.44 coefficient accounts for the fact that not all free throws end a possession (technical foul free throws, and-one situations, and three-shot fouls). Game pace is typically calculated as the average of both teams possessions since the possession count should be roughly equal for both teams in a game. The NBA league average pace has fluctuated from around 90 possessions per game in the mid-2000s slow-it-down era to approximately 100 possessions in the modern pace-and-space era.
What is offensive rating and why is it more useful than points per game?
Offensive rating measures points scored per 100 possessions, providing a pace-independent measure of offensive efficiency. Points per game is heavily influenced by tempo. A team scoring 115 points per game might seem elite, but if they use 110 possessions, their offensive rating is only 104.5, which is merely average. Conversely, a team scoring 100 points on only 90 possessions has an offensive rating of 111.1, which is excellent. Historical context: the best offenses typically post ratings of 115 or higher, average offenses sit around 108 to 112, and poor offenses fall below 105. At the player level, offensive rating estimates points produced per 100 possessions while on the floor, helping evaluate individual scoring efficiency independent of playing time and team tempo.
How do you calculate pace-adjusted statistics for player comparisons?
To pace-adjust individual player statistics, first calculate the per-minute or per-possession rate, then normalize to a standard reference (typically per 36 minutes or per 100 possessions). For per-100-possessions stats: Adjusted Stat = (Raw Stat / Minutes Played) x (48 / Team Pace) x 100. For example, if a player scores 20 points in 30 minutes with a team pace of 100: Per-minute rate = 20/30 = 0.667 points per minute. Per-100-possessions = 0.667 x (48/100) x 100 = 32.0. This is more informative than raw totals because a player on a fast team accumulates more counting stats simply from having more possessions. Pace adjustment reveals that a player averaging 18 points on a 95-pace team may be more efficient than one averaging 22 points on a 110-pace team.
What is net rating and how does it predict team success?
Net rating is the difference between offensive rating and defensive rating, representing how many more (or fewer) points a team scores than it allows per 100 possessions. It is widely considered the single best predictor of team quality and future success, outperforming win-loss record, point differential, and most other metrics. A positive net rating indicates outscoring opponents on a per-possession basis. Historical benchmarks: championship-caliber teams typically maintain net ratings of plus-6 or higher, playoff teams average plus-2 to plus-6, average teams hover around zero, and lottery teams are minus-3 or worse. Net rating is especially valuable for identifying teams whose records are inflated by close-game luck or deflated by bad luck in tight contests, making it a favorite metric for projections and betting analysis.
Why do the two teams in a game end up with slightly different possession counts?
In principle the totals are nearly identical, because possessions alternate and only the team that ends a quarter or grabs the last rebound can gain one extra. The gaps you see come from estimation: the box-score formula FGA - OREB + TOV + 0.44 x FTA infers possessions rather than counting them, and the 0.44 free-throw term is an average that fits and-ones, technical shots, and three-shot fouls imperfectly. That is why game pace is reported as the average of the two figures rather than either one alone.
How do you convert pace into average seconds per possession?
A regulation game runs 48 minutes, or 2,880 seconds, and both teams share that clock. With pace expressed as possessions per team, the total number of possessions is twice the pace, so average possession length is 1,440 divided by pace. A pace of 100 works out to 14.4 seconds per trip, well under the 24-second shot clock because transition buckets, early offense, and quick turnovers pull the average down. A pace of 90 stretches each trip to 16 seconds.
Does playing at a faster pace help a team win?
Pace is close to neutral for expected margin, since both teams get roughly the same number of possessions and it is efficiency per possession that decides the outcome. What pace changes is variance. More possessions push the result toward the better team's true quality, which favours the stronger side, while a slow, grinding game gives an underdog a better chance of an upset. Tempo also matters for fit: a team should play the speed that maximises its own net rating, not the speed that produces the biggest scoreboard number.
How do you project a game total from ratings and pace?
Take the two teams' expected possessions to set a game pace, then apply each side's efficiency: projected points equal offensive rating multiplied by expected possessions divided by 100. A team rated 112 against an opponent that allows 108 blends to about 110 points per 100; at 98 possessions that projects to roughly 108 points, and the same arithmetic run the other direction gives the opposing side's total. This is why raw scoring averages mislead when a fast team meets a slow one: the pace they settle on drives the total more than either offense does.
Why did NBA teams score more points per game in the 1960s than they do now?
Tempo, not efficiency. Teams in that era ran far more possessions per game, sometimes well over 120, so raw point totals climbed even though scoring per possession was poor by modern standards. Offensive ratings then sat below today's marks, with lower shooting percentages and no three-point line to raise the value of a jump shot. Pace adjustment is what makes cross-era comparison meaningful: converting to points per 100 possessions strips out the tempo difference and leaves the actual efficiency gap.
