What is the best basketball tactic? I simulated 153,936 games with 8 offenses and 8 defenses
There is no single best basketball tactic in Swish & Dunk: in 153,936 games between identical teams, every offense won between 48.8% and 51.0% of its games and every defense between 48.6% and 51.5%. What decides a game is the matchup. Small Ball beats Drop Coverage 58.5% of the time, while the Triangle wins only 40.0% against the same defense. It was not always like this: the first time I ran this experiment, the Princeton offense won 62.3% of its games, and I had to rebalance the game.
Results at a glance
- No dominant tactic: offenses between 48.8% and 51.0%, defenses between 48.6% and 51.5%, with a margin of error of ±1.1 points.
- The matchup decides: depending on the defense it faces, the same offense goes from 40.0% to 58.5%.
- Shooters beat paint defenses: Small Ball (58.5%), 5-Out (57.1%) and Pace and Space (56.1%) beat Drop Coverage, but lose to Switch-Everything (Small Ball 42.5%).
- Inside and passing beat switches and pressure: the Triangle wins 58.3% against Switch-Everything, Princeton 56.7% against the Full-Court Press. Both suffer against Drop Coverage (Triangle 40.0%).
- Before the rebalance one tactic ruled: Princeton won 62.3%, the Full-Court Press 58.5%, the two together 71.5%. Today the same combination wins 52.7%.
How I ran the experiment
Every number in this article comes from the match engine that plays every official Swish & Dunk game, simulating each possession from the players' ratings. I did not use league results, because in a real league the better roster usually wins and that hides the effect of the tactic. I built a laboratory instead.
- Identical teams. I took three typical rosters from the league and cloned each one on both sides of the court: a Division 1 roster (average Overall 83.3, 12 players), a Division 5 roster (79.5, 12 players) and a Division 10 roster (70.8, 15 players). Both teams have the same players, full fitness and the same default rotation. The only difference is the tactic.
- Four tests. The 8 offenses played each other in every pairing (28 pairings, 360 games per pairing and roster: 30,240 games). The 8 defenses did the same (30,240 games). Then every offense faced every defense (64 pairings, 1,404 games each: 89,856 games). Finally I tested the best offense together with the best defense of the first run (3,600 games).
- A neutral opponent. When a test changes only the offense, both teams defend with the "fair mix": the average of all 8 defenses, the same profile the engine uses for a team that has not chosen a tactic. It works the same way for the defense tests.
- Reproducible. Home and away alternate, and every game has a fixed random seed, so running the experiment again gives exactly the same numbers. The margin of error is about ±1.1 percentage points for the offense and defense rankings and ±2.6 for each cell of the matrix.
The data is public: you can download every game as a compressed CSV file (one row per game, with points, possessions, threes and turnovers for both teams), the summary of the results and the summary of the first run, before the rebalance.
The 16 tactics in the test
Swish & Dunk has 8 offensive and 8 defensive systems, and each one changes the way the engine plays a possession: tempo, shot selection, ball movement, turnover risk, contests and rebounding. The guide to every offense and defense explains them all; the names in the tables below link to the guide of each system.
- Offenses: Princeton, Motion and the Triangle move the ball and cut; Spread Pick-and-Roll lives on the pick-and-roll; 5-Out, Pace and Space and Small Ball spread the floor for threes; Run and Gun pushes the pace in transition.
- Defenses: the Full-Court Press and the Half-Court Trap hunt turnovers; Man-to-Man is the classic one-on-one; Switch-Everything changes on every screen; Match-Up Zone mixes zone and man; No-Middle, Pack Line and Drop Coverage protect the paint.
The first run: one tactic ruled the game
The first version of this experiment, 51,312 games with the original tactics, produced a clear winner. The Princeton offense won 62.3% of its games, Motion 58.2% and the Triangle 57.2%, while Run and Gun won only 35.6%. On defense the Full-Court Press won 58.5% and Pack Line 39.5%. Princeton with the press beat an identical team 71.5% of the time.
The cause was a single factor: turnovers. Princeton lost 10.6 balls per game, Run and Gun 20.4, and the press forced 22.2 per game. In a basketball manager game that is a problem: if one system always wins, every manager copies it and the choice of tactic stops mattering.
| Tactic | First run (before) | Today (after) |
|---|---|---|
| Offenses | ||
| Princeton | 62.3% | 50.9% |
| Motion | 58.2% | 50.1% |
| Triangle | 57.2% | 48.8% |
| Spread Pick-and-Roll | 51.0% | 50.3% |
| Small Ball | 45.8% | 51.0% |
| 5-Out | 45.7% | 50.0% |
| Pace and Space | 44.2% | 49.7% |
| Run and Gun | 35.6% | 49.3% |
| Defenses | ||
| Full-Court Press | 58.5% | 50.5% |
| No-Middle | 54.8% | 51.4% |
| Half-Court Trap | 54.6% | 51.5% |
| Switch-Everything | 52.3% | 50.7% |
| Match-Up Zone | 51.9% | 49.2% |
| Man-to-Man | 45.4% | 48.9% |
| Drop Coverage | 42.9% | 48.6% |
| Pack Line | 39.5% | 49.2% |
What I changed in the game
I made two changes to the Swish & Dunk match engine, both tested with the same laboratory before going live.
- Turnovers rebalanced. I retuned only the two values that decided the first run: the turnover risk of each offense and the turnovers forced by each defense. An automatic calibration moved each tactic toward 50% against the fair mix: Princeton went from 0.85 to 0.99, Run and Gun from 1.20 to 1.02, the Full-Court Press from 1.35 to 1.24, Pack Line from 0.85 to 0.97. The league average did not change, so the game keeps the same number of turnovers. Pace, shot selection, ball movement, contests and rebounding stayed the same, so every system keeps its identity.
- Matchups added. Every shot now gets a small bonus or penalty that depends on the offense against the defense, along three axes: three-point shooting against perimeter contest, the inside game against rim protection, and ball movement against defenses that hunt turnovers. The effect is zero against the fair mix, so it does not make any tactic stronger on average: it decides who beats whom.
Which offense wins the most today?
None by a clear margin. The 8 offenses finished between 48.8% and 51.0%, and most differences are within the ±1.1 margin of error: Small Ball (51.0%), Princeton (50.9%), Spread Pick-and-Roll (50.3%), Motion (50.1%), 5-Out (50.0%), Pace and Space (49.7%), Run and Gun (49.3%) and the Triangle (48.8%).
| Offense | Win % | Point margin | Points per 100 possessions | Possessions | Turnovers | Shots from three |
|---|---|---|---|---|---|---|
| Small Ball | 51.0% ±1.1 | +0.4 | 117.0 | 103.3 | 13.4 | 48.4% |
| Princeton | 50.9% ±1.1 | +0.2 | 117.0 | 96.3 | 13.7 | 44.9% |
| Spread Pick-and-Roll | 50.3% ±1.1 | +0.1 | 116.8 | 99.8 | 14.3 | 43.7% |
| Motion | 50.1% ±1.1 | +0.1 | 116.8 | 99.5 | 14.5 | 44.1% |
| 5-Out | 50.0% ±1.1 | +0.1 | 117.0 | 100.8 | 12.5 | 48.3% |
| Pace and Space | 49.7% ±1.1 | -0.2 | 116.7 | 102.7 | 14.4 | 49.0% |
| Run and Gun | 49.3% ±1.1 | -0.3 | 116.8 | 107.2 | 15.7 | 41.1% |
| Triangle | 48.8% ±1.1 | -0.4 | 116.5 | 97.6 | 14.6 | 39.8% |
The styles are still very different: Run and Gun plays 107.2 possessions per game and Princeton 96.3, Pace and Space takes 49.0% of its shots from three and the Triangle 39.8%. They simply reach almost the same efficiency, about 117 points per 100 possessions, by different roads.
Which defense wins the most today?
The Half-Court Trap (51.5%) and No-Middle (51.4%) lead by a hair over Switch-Everything (50.7%) and the Full-Court Press (50.5%); Drop Coverage closes at 48.6%. The press is still the defense that forces the most turnovers, 19.5 per game against about 14 for a balanced defense, but it pays for them with more possessions and fouls.
| Defense | Win % | Point margin | Points allowed per 100 possessions | Turnovers forced | Possessions |
|---|---|---|---|---|---|
| Half-Court Trap | 51.5% ±1.1 | +0.4 | 116.5 | 17.7 | 101.6 |
| No-Middle | 51.4% ±1.1 | +0.4 | 116.3 | 12.7 | 99.6 |
| Switch-Everything | 50.7% ±1.1 | +0.1 | 116.6 | 14.1 | 99.7 |
| Full-Court Press | 50.5% ±1.1 | +0.3 | 116.4 | 19.5 | 104.6 |
| Match-Up Zone | 49.2% ±1.1 | -0.3 | 117.3 | 10.8 | 99.4 |
| Pack Line | 49.2% ±1.1 | -0.2 | 117.3 | 12.3 | 100.6 |
| Man-to-Man | 48.9% ±1.1 | -0.2 | 117.2 | 13.8 | 100.0 |
| Drop Coverage | 48.6% ±1.1 | -0.5 | 117.5 | 12.1 | 100.3 |
Offense against defense: the full matrix
This is where tactics make the difference. Every cell is the win percentage of a team using the offense in the row against an identical team using the defense in the column. Green means the offense wins more often, red means the defense does.
| Offense ↓ / Defense → | Half-Court Trap | No-Middle | Switch-Everything | Full-Court Press | Match-Up Zone | Pack Line | Man-to-Man | Drop Coverage |
|---|---|---|---|---|---|---|---|---|
| Small Ball | 49.5 | 52.8 | 42.5 | 46.2 | 46.4 | 56.4 | 50.9 | 58.5 |
| Princeton | 54.6 | 51.1 | 54.6 | 56.7 | 52.6 | 46.5 | 52.1 | 46.8 |
| Spread Pick-and-Roll | 46.9 | 49.3 | 50.7 | 46.7 | 51.1 | 51.1 | 50.9 | 49.6 |
| Motion | 49.9 | 48.5 | 53.3 | 49.6 | 48.6 | 46.4 | 49.9 | 46.0 |
| 5-Out | 49.4 | 48.1 | 48.6 | 48.7 | 47.3 | 54.6 | 49.2 | 57.1 |
| Pace and Space | 48.1 | 49.1 | 44.5 | 47.1 | 48.2 | 55.8 | 49.1 | 56.1 |
| Run and Gun | 46.4 | 46.4 | 53.3 | 46.2 | 56.3 | 47.1 | 52.6 | 49.9 |
| Triangle | 46.0 | 47.1 | 58.3 | 51.1 | 54.6 | 43.8 | 50.9 | 40.0 |
Win % of the team using the offense in the row against an identical team using the defense in the column. 1,404 games per cell, margin of error about ±2.6 points.
- The most lopsided matchups: Small Ball against Drop Coverage (58.5%, 120.8 points per 100 possessions) and the Triangle against Switch-Everything (58.3%). The opposite extreme is the Triangle against Drop Coverage: 40.0% and 113.4 points per 100.
- Against Drop Coverage, shoot: Small Ball 58.5%, 5-Out 57.1%, Pace and Space 56.1%. Against Pack Line the same three win between 54.6% and 56.4%.
- Against Switch-Everything, go inside: the Triangle wins 58.3%, Princeton 54.6%, Motion and Run and Gun 53.3%. Small Ball falls to 42.5%.
- Against the press and the trap, pass: Princeton wins 56.7% against the Full-Court Press and 54.6% against the Half-Court Trap. Run and Gun stops at 46.2% and 46.4%.
- Against Match-Up Zone, run: Run and Gun wins 56.3%, the Triangle 54.6%.
| Offense | Best matchup | Worst matchup |
|---|---|---|
| Small Ball | Drop Coverage 58.5% | Switch-Everything 42.5% |
| Princeton | Full-Court Press 56.7% | Pack Line 46.5% |
| Spread Pick-and-Roll | Match-Up Zone 51.1% | Full-Court Press 46.7% |
| Motion | Switch-Everything 53.3% | Drop Coverage 46.0% |
| 5-Out | Drop Coverage 57.1% | Match-Up Zone 47.3% |
| Pace and Space | Drop Coverage 56.1% | Switch-Everything 44.5% |
| Run and Gun | Match-Up Zone 56.3% | Full-Court Press 46.2% |
| Triangle | Switch-Everything 58.3% | Drop Coverage 40.0% |
Why some matchups win and others lose
Three rules explain almost the whole matrix. They come from the identity of each system, the same values described in the guide of every tactic.
- Three-point shooting against perimeter contest. Drop Coverage and Pack Line sag toward the paint and contest the perimeter less (×0.85), so offenses built on threes punish them. Switch-Everything and Match-Up Zone contest the perimeter more (×1.10) and take those shots away.
- Inside game against rim protection. Drop Coverage has the strongest interior contest in the game (×1.30) and Pack Line follows (×1.20): the Triangle and Princeton, which live near the basket, suffer against them. Switch-Everything and the press protect the rim less (×0.90), and the inside game exploits them.
- Ball movement against pressure. The press and the trap are built to force turnovers; offenses that move the ball a lot, like Princeton (×1.30), turn that pressure into open shots. Offenses that move it little, like Run and Gun (×0.90), give the press what it wants.
Turnovers still matter, as Dean Oliver's "four factors" explain in the guide to analyzing basketball stats, but they are no longer the only thing that decides a game.
How to choose your tactic
The practical rule is to look at the opponent's system and pick the counter.
- If the opponent plays Drop Coverage or Pack Line, use Small Ball, 5-Out or Pace and Space.
- If it plays Switch-Everything, use the Triangle, Princeton, Motion or Run and Gun.
- If it plays the Full-Court Press or the Half-Court Trap, use Princeton.
- If it plays Match-Up Zone, use Run and Gun or the Triangle.
- On defense, answer shooters with Switch-Everything, the Triangle and Princeton with Drop Coverage or Pack Line, and Run and Gun or Spread Pick-and-Roll with the press or the trap.
Does it depend on the team?
Very little. I repeated every test with three rosters of very different quality, and no tactic left the 46-53% range at any level. Small Ball won 51.1% with the Division 1 roster, 50.6% with the Division 5 one and 51.4% with the Division 10 one; the Triangle 48.6%, 48.0% and 49.7%. The right tactic matters as much for a Division 10 club as for a Division 1 club.
| Tactic | Division 1 (OVR 83.3) | Division 5 (OVR 79.5) | Division 10 (OVR 70.8) |
|---|---|---|---|
| Offenses | |||
| Small Ball | 51.1% | 50.6% | 51.4% |
| Princeton | 51.9% | 50.1% | 50.7% |
| Spread Pick-and-Roll | 49.9% | 50.8% | 50.1% |
| Motion | 49.9% | 49.6% | 50.8% |
| 5-Out | 50.8% | 51.3% | 47.8% |
| Pace and Space | 48.9% | 49.8% | 50.4% |
| Run and Gun | 48.9% | 49.7% | 49.1% |
| Triangle | 48.6% | 48.0% | 49.7% |
| Defenses | |||
| Half-Court Trap | 50.7% | 51.8% | 52.0% |
| No-Middle | 52.0% | 51.7% | 50.5% |
| Switch-Everything | 50.3% | 51.1% | 50.8% |
| Full-Court Press | 49.1% | 52.0% | 50.4% |
| Match-Up Zone | 50.4% | 49.4% | 47.8% |
| Pack Line | 48.7% | 48.3% | 50.7% |
| Man-to-Man | 48.7% | 49.5% | 48.4% |
| Drop Coverage | 50.0% | 46.2% | 49.4% |
Is there still a winning combination?
No. Princeton with the Full-Court Press, the combination that won 71.5% in the first run, now wins 52.7% of 3,600 games (±1.6) against an identical team playing the fair mix, by 0.8 points on average: 52.5% in Division 1, 52.0% in Division 5 and 53.5% in Division 10. There is no tactic to copy and forget: the advantage comes from reading the opponent.
What it says about real basketball
These results describe the Swish & Dunk simulator after the October 2026 rebalance, not every level of real basketball. The three matchup rules follow real coaching logic: switching on every screen takes threes away but invites mismatches inside, a sagging defense protects the rim but leaves shooters open, and passing is the classic answer to pressure. Real basketball adds much more: adjustments during the game, set plays, player habits and scouting do not exist in this experiment.
The first run is also an honest lesson about simulators: a model that looks reasonable can hide a dominant strategy until you test it on thousands of games. If the engine changes again, I will run the experiment again and update this page.
Think you can read the opponent better than the lab?
I tested 16 tactics on identical teams. In the game, your roster is unique and every opponent plays its own system: your shooters, your big men and your playmakers can change which counter works best. Pick your system, look at what the other team plays and see if you can turn the matchup in your favor.
