Does trash talk
actually work?
No. I tested it 3 ways: talk in the media during the playoffs, taunts on the court, and the players who talk all game, every game. On average trash talk changes nothing, and a taunt costs your team about 0.6 points.
For almost everybody, trash talk doesn't work. It doesn't win playoff series, it doesn't get in anyone's head at the free-throw line, and a taunt costs about 0.6 points. Jordan, Garnett, Kobe and Luka get no edge the numbers can see either. The players they did it to say it worked, but that's testimony, not proof.
Teams whose players talked in the media, judged on the 224 playoff games after the talk (62 series since 1993).
The fake lists are playoff teams in the exact same spot in a series, like down 2 games to 1. Talkers shot −0.7 points of true shooting vs normal, targets −0.5. Verdict: nothing.
2,259 taunts since 1997: a technical foul within 5 seconds of the player's own team making a big play. Net points over the next 2 minutes.
Compared with about 3.5 million matched moments: the same kind of play, at the same score and time, with no taunt. The taunter's next 3 shots: 1,440 made vs 1,454 expected. Verdict: it hurts.
Free throws opponents shot with 35 famous talkers on the floor (401,591 of them), each compared with that shooter's own percentage.
Only 4% of 10,000 fake lists of ordinary players did better, but the gap is tiny. In the last 5 minutes of close games it's zero (59% of fake lists did better). Verdict: tiny.
Watch the 3 tests get built, plus what Bosh, Larry Johnson and Nurkić said it felt like.
My play-by-play starts in 1997, so it only covers Jordan's last 2 seasons in Chicago and his 2 in Washington (18 technicals: too few to trust). Garnett came closest, but even that's within luck. Kobe's opponents missed more free throws with him on the floor, and even more when he sat, so that's the Lakers, not Kobe.
The famous cases lost more than they should have. Everything I found by searching every postseason won right where it should have. So trash talk probably doesn't backfire. People just remember the times it did, because a guy talking big and then losing is the better story.
All 62 playoff series
One row per series: the first player who talked. Expected wins are for the games after the talk. Tap a column to sort; “Famous” marks the cases from the well-known lists.
Opponents' free throws vs 35 talkers
Opponents' FT% with him on the floor, minus each shooter's own FT%, regular season 1997–2025. For comparison, ordinary players' fake lists land around −0.17. Clutch = last 5 minutes, within 5 points.
How the model works
V1 · The raw record
Teams whose players talked won only 24 of 62 series (39%). That makes trash talk look like it backfires, but 41 of those 62 teams were the underdog.
V2 · An expected result for every game
Each game gets an expected result from the two teams' regular seasons and home court. I backtested it, meaning I checked its odds against games that already happened: all 3,566 playoff games since 1980. Said vs won: 56% → 58% · 65% → 65% · 74% → 76% · 83% → 83%.
V3 · Expected vs actual
After the talk, those teams were expected to win 105.8 games. They won 105. In other words, they won almost exactly as often as they should have.
V4–V5 · 10,000 fake lists
The real talkers against 10,000 fake lists of playoff teams in the same spot in a series. 28% of the fake lists did better than the real talkers.
Taunts vs a matched control
The play-by-play stopped labelling taunts, so a taunt is a technical within 5 seconds of the player's own team making a big play. The raw numbers mislead, because after you score the other team gets the ball. So each taunt is compared with the same kind of play, at the same score and time, with no taunt.
Free throws vs career talkers
Nobody can guard a free throw, so if trash talk gets in your head, it should show up there. Each opponent free throw is compared with the shooter's own percentage, then the talkers are compared with 10,000 fake lists of ordinary players.
The greats, separately
Every test again on just Jordan, Garnett, Kobe and Luka. The interviews in the video (Bosh, Larry Johnson, Nurkić, Payton) are testimony, not proof.
Data: NBA play-by-play 1996-97 to 2024-25 (more than 21,000 technical fouls), Basketball-Reference team ratings and playoff results, and 90 documented trash-talk cases from news reports. Bill Laimbeer, Isiah Thomas and Larry Bird played before the play-by-play starts.
