Halfway through the second quarter at Madison Square Garden last night, the San Antonio Spurs were ahead 76-49. Twenty-seven points up. In Game 4 of the NBA Finals. On the road. Against a Knicks team that had won 13 straight playoff games. Their biggest lead of the night was 29.

Then they did something no Spurs team has done in 30 years of playoff basketball: they completely fell apart.

Final: Knicks 107, Spurs 106.

A one-point loss. After leading by 29. In an NBA Finals game. The Knicks now lead the series 3-1, are one win away from their first championship since 1973, and the Spurs are going home for Game 5 having authored the kind of collapse that Spurs fans are going to have nightmares about for the rest of their lives.

Let me try to put this into words, because the box score doesn't quite do it justice.

What Actually Happened

The scoring by quarter is genuinely hard to read without flinching:

1st quarter: Spurs 41, Knicks 22. (Spurs +19) 2nd quarter: Spurs 35, Knicks 27. (Spurs lead 76-49 at half — +27) 3rd quarter: Knicks 26, Spurs 14. (Knicks -1 entering Q4) 4th quarter: Knicks 32, Spurs 16. (Knicks win by 1)

The Spurs scored 76 points in the first half of an NBA Finals game on the road. They were the most dominant offensive team in basketball for 24 minutes. Wemby was attacking. Vassell was hitting from deep (6-of-9, 18 points). Dylan Harper was carving up the Knicks defense (8-of-12 for 21 points, with the swagger of a 19-year-old who didn't know he was supposed to be intimidated). The Spurs hit 17 threes on 43 attempts (39.5%). They had 24 assists to only 12 turnovers. They outshot the Knicks from three. They outshot them from the line. They got 28 bench points to the Knicks' 12.

By every conventional measure, the Spurs played better basketball than the Knicks for 48 minutes.

They still lost.

Because basketball isn't measured by 48 minutes. It's measured by the 30 minutes in the middle when you have a 27-point lead — and the 18 minutes after that when you have to actually hold it.

The Half That Won't Stop Replaying

Let's stay in the moment for a second. The Knicks outscored the Spurs 58-30 in the second half. That's a 28-point swing across the final 24 minutes of an NBA Finals game.

The third quarter is where the air left the building. Knicks 26, Spurs 14. San Antonio went almost six minutes without scoring at one stretch. Wemby's shot stopped falling. The Spurs' role players froze. Coach Mitch Johnson tried timeouts. He tried lineup changes. He tried double-teaming Brunson. None of it worked.

The Knicks just kept coming.

The fourth quarter was a coronation. Knicks 32, Spurs 16. A 16-point quarter loss in the biggest game of the season with a 27-point first-half lead in the bank. The Garden crowd, which had been quiet through most of the first half, transformed into the loudest building in basketball over those final 12 minutes. Every Knicks bucket got an MSG roar. Every Spurs miss got a sigh.

By the time the score got to 105-104 with under a minute left, you could see it on the Spurs' faces. They weren't shocked. They were resigned. They knew the collapse was happening. They knew there was nothing left to do about it.

Brunson hit a clutch shot. Wemby missed. The buzzer sounded. Madison Square Garden lost its mind.

The Spurs lost their season. Probably.

Where This Ranks Historically

A 29-point lead. Blown. In an NBA Finals game.

Let's run through the comparable collapses in NBA playoff history:

• 2024 Pacers vs Knicks (East Semis Game 7): The Pacers gave up a 12-point fourth-quarter lead. Different game, different context.
• 2016 Warriors vs Cavs Game 7: Warriors led most of the night before losing 93-89. Not a true blown-lead game.
• 2008 Celtics vs Lakers Finals Game 4: Lakers led by 24 in the third quarter, lost by 6.
• 1957 Celtics vs Hawks Finals Game 7: Hawks led by 15 early, lost in double overtime.

The 2026 Spurs blew 29. In a Finals game. The largest collapse of a fourth-quarter-secure lead in NBA Finals history is being debated this morning on every basketball show in America, but the case for Game 4 being the worst Finals collapse in the modern era is now genuinely strong.

For comparison, the Spurs' biggest lead in Game 1 of this series was 14 — and they lost that one too. So they've now blown a 14-point lead and a 29-point lead in the same NBA Finals series. That's a wild psychological undercurrent heading into Game 5.

OG Anunoby Just Authored the Game of His Life

Let's actually celebrate the Knicks side, because they didn't just get lucky — they got one of the greatest single-game shooting performances in NBA Finals history.

OG Anunoby: 33 points. 10-of-15 from the field. 7-of-9 from three (77.8%). 6-of-6 from the line. +/- of -1.

Read that again. Seven made threes on nine attempts. In an NBA Finals game. From a guy who came into the series shooting 36% from deep. Anunoby's shooting line in the second half alone was the difference in the entire game — he was the player who physically dragged the Knicks back into it, hitting shot after shot whenever the Spurs threatened to extend the lead back out.

Without OG's night, this game is a comfortable Spurs win. The Spurs should have won by 12. Anunoby just refused to let them.

Brunson Was Brunson

And of course, the captain.

Jalen Brunson: 36 points, 5 rebounds, 7 assists, 3 steals. 12-of-25 from the field, 9-of-11 from the line. +/-: +11.

When the game got tight in the fourth quarter, Brunson did what he's done all postseason: he got to the rim and the line. Fourteen of his 36 points came in the paint. He drew 8 fouls. He hit his free throws. He ran the offense without forcing it (3 turnovers, 2.33 assist-to-turnover ratio). And when the moment got the biggest in the final minute, he hit the shot that put New York ahead for good.

He's not the loudest superstar in the league. He doesn't have the highlight-reel highlights of an SGA or a Wemby or a Tatum. He's just the guy in your guard's hip pocket who's slowly grinding you into the floor for 38 minutes a night and somehow has 36 points before you realize what's happening.

KAT Showed Up Quietly

Karl-Anthony Towns: 13 points, 10 rebounds, 2 assists. 4-of-5 from the field. 1-of-1 from three. 4-of-4 from the line.

Quiet line — but a +17 plus/minus in his minutes, which led the team. KAT didn't take a ton of shots, but his big-man presence inside (6 points in the paint), his rebounding (10 boards), and his stretch shooting (perfect from three) helped tilt the floor when the Knicks really needed it. Sometimes basketball impact isn't 35 points. Sometimes it's a quietly-excellent double-double in a game your team comes back from 29 down to win.

What Went Wrong for the Spurs

Outside of the basic "they stopped scoring" narrative, here are the specific failures:

Wemby disappeared offensively. Wembanyama went 9-of-25 (36%) from the field, 2-of-8 from three, and just 4-of-7 from the line. He had 24 points, 13 rebounds, and 3 blocks — and a +1 plus/minus that vastly undersells how poorly his offensive game went. He went to the line 7 times and missed 3 of them. He took 17 shots in the paint and made just 6. When the Spurs needed Wemby to be the great equalizer in the fourth quarter, his shot just wasn't there.

He also picked up a flagrant foul. For the second time in three games, Wemby got tagged with a flagrant in the Finals — extending the "is Wemby a dirty player?" conversation that already had three weeks of fuel on it.

Stephon Castle struggled. 13 points on 2-of-7 from the field, 5 personal fouls, 3 turnovers, -11 plus/minus. Castle's been inconsistent all series, and Game 4 was his worst performance.

De'Aaron Fox went cold. 18 points on 6-of-16 (37.5%), 4 turnovers, only 18 points despite hitting 4 threes. Fox couldn't get into a rhythm in the second half when the Spurs needed him most.

The depth advantage evaporated. The Spurs' bench outscored the Knicks' bench 28-12 in the game — but most of those bench points came in the first half when the Spurs were building the lead. In the second half, when the Knicks' role players (especially Anunoby) took over, the Spurs' bench was nowhere to be found.

The free-throw line. Spurs were 17-of-20 (85%). Fine. Knicks were 20-of-28 (71.4%) but went to the line 8 more times — and one of those extra attempts was the Wembanyama-flagrant trip that became a 3-shot trip for OG late in the third. Tiny margins. Big consequences.

What This Means

The Knicks lead the NBA Finals 3-1.

Teams that go up 3-1 in the NBA Finals have won the title 38 out of 39 times in league history. The lone exception was the 2016 Warriors, who blew a 3-1 lead to Cleveland. Every other 3-1 Finals lead has resulted in a championship.

The Knicks are 13-1 in the playoffs. They have not lost a game since April 23. They have not lost two straight games since January 7. They are playing the best basketball of any team in the league for two straight months.

And they're one win from the title.

The win probability model now gives the Knicks an 89.3% chance to win this series. The Spurs would need to win Game 5 in San Antonio (which they could — they're 6-1 at home this postseason), then Game 6 at MSG (an unprecedented road win for a team that has now lost three straight at the Garden), then Game 7 in San Antonio. Three straight wins, including a road game at the loudest arena in basketball. Against a Knicks team playing championship-level basketball.

It's possible. It's also profoundly unlikely.

What's Next

Game 5: Saturday, June 13. 8:30 PM ET. San Antonio.

If the Knicks win, they're champions. The trophy gets handed out in San Antonio. Brunson gets his first ring. Mike Brown wins Coach of the Year and a title in his first season at the helm. Walt "Clyde" Frazier and Patrick Ewing get to see this generation of Knicks finish what their generation couldn't.

If the Spurs win, the series shifts back to MSG for Game 6 on Tuesday night. The pressure stays squarely on New York to finish at home. Wemby gets one more game to write a different ending.

For Knicks fans who waited 53 years for the franchise to be in this position: enjoy the next 48 hours. The Knicks are about to win the NBA championship. The math is overwhelming. The momentum is undeniable. The Spurs are wounded — physically and psychologically — in a way that's hard to come back from.

For Spurs fans: tonight is going to be tough. A 29-point lead in an NBA Finals game, blown. The kind of loss that sticks. But this team has the best young core in basketball. Wemby is 22. Castle is 22. Harper is 19. The future is bright. It's just not going to include a title in 2026, in all likelihood.

For everyone else: this is what playoff basketball is supposed to be. Wild swings. Historic collapses. Improbable comebacks. Generational players doing impossible things. One game from a championship for a franchise that hasn't won one in 53 years.

The Spurs led by 29. They lost by 1. The Knicks are one win away. Game 5 is Saturday.

What a ride.

Game 5: Saturday, June 13 at 8:30 PM ET on ABC. The Knicks lead the NBA Finals 3-1.
