Both Conference Finals Went to Overtime Last Night. The NBA Has Never Seen a Week Like This One.

NEW YORK, May 20, 2026 —

Key Takeaways:

• The New York Knicks erased a 22-point fourth-quarter deficit to defeat the Cleveland Cavaliers 115-104 in overtime Tuesday night — the largest comeback in Knicks playoff history and the second-largest fourth-quarter playoff comeback in the play-by-play era — behind 38 points from Jalen Brunson
• For the first time in NBA history, both Conference Finals Game 1s went to overtime on back-to-back nights — Wembanyama’s double-overtime classic in OKC on Monday followed by Brunson’s fourth-quarter resurrection at MSG on Tuesday — a sequence that has no precedent in the playoff record books
• The Knicks targeted James Harden 21 times in isolation in the fourth quarter and overtime — Harden gave up 1.9 points per play on those possessions, the kind of number that will define the Cleveland team’s tactical problem for the rest of this series

On Monday night, Victor Wembanyama scored 41 points and 24 rebounds and the Spurs beat the defending champions in double overtime in Oklahoma City. On Tuesday night, Jalen Brunson scored 38 points, erased a 22-point deficit at Madison Square Garden, and delivered what may be the single greatest fourth-quarter performance in Knicks playoff history. Back-to-back nights. Back-to-back overtimes. Both Conference Finals. It has never happened before in the NBA.

The league needed a week like this. It got one in 48 hours.

The Fourth-Quarter Collapse That Became the Greatest Comeback in Garden History

The Cavaliers were in complete control. Cleveland led 93-71 with 7:52 remaining in the fourth quarter. The Knicks had shot 2-of-19 from three-point range in the first half. Karl-Anthony Towns had picked up foul trouble. Madison Square Garden — loud for three quarters — had gone to a particular kind of silence that arena crowds produce when they have begun to accept a loss.

Then Brunson decided he was done accepting it. He attacked James Harden in isolation, drawing fouls, converting at the line, and making the Cavaliers’ defensive scheme look like a blueprint he had already memorized. The Knicks outscored Cleveland 44-11 from that moment through the end of overtime — a 12-minute, 39-second sequence in which New York shot 75% from the field and 6-of-8 from three, while Cleveland shot 22.2% and turned the ball over six times.

Brunson finished with 38 points, six assists, five rebounds, and three steals. He scored 17 of those points in the fourth quarter and overtime alone, shooting 8-of-10 on the night’s most critical possessions. The comeback was the largest in Knicks postseason history and the second-largest fourth-quarter playoff comeback in the play-by-play era. Teams leading by 22 in the fourth quarter had gone 594-1 over the previous 30 postseasons before Tuesday night. The Cavaliers became the one.

What Harden Did — and Did Not Do — When It Mattered Most

The tactical decision the Knicks made was not subtle. They found James Harden and they kept going back to him. In the fourth quarter and overtime, Brunson pulled Harden into 21 on-ball screen situations. Those 21 possessions resulted in nine isolations. Brunson scored or assisted on all nine. The average yield per play against Harden on those possessions was 1.9 points — a number so favorable to New York that opposing coaches will spend the next 48 hours designing their own version of it.

Donovan Mitchell had finished with 29 points, five rebounds, and six steals — a dominant first-three-quarter performance that positioned Cleveland as heavy favorites heading into the stretch. Mitchell disappeared in crunch time. The Cavaliers shot 22% over the final 12 minutes. Their offense, which had been flowing through Mitchell and taking advantage of Cleveland’s pace, went completely static when the Knicks took away their spacing and forced the ball into situations where Harden was the decision-maker under pressure.

Game 2 is Thursday at Madison Square Garden. The team that wins Game 1 of a Conference Finals series has advanced to the NBA Finals 78.2% of the time in NBA history. The Knicks have won 8 consecutive games heading into Thursday. The Cavaliers have to solve the Harden problem, find Mitchell’s crunch-time involvement, and do both on the road at the loudest arena in basketball.

Game 2 West Tonight — OKC Seeks Equilibrium After Wembanyama’s Statement

While the Garden absorbed Tuesday night’s events, Oklahoma City was preparing for Game 2 of the Western Conference Finals at Paycom Center. After absorbing Wembanyama’s 41-point, 24-rebound masterpiece on Monday — a performance that cost the Thunder their first home loss in 31 games this postseason — the focus in OKC has shifted to what Shai Gilgeous-Alexander and the Thunder coaching staff do differently.

The primary adjustment involves Chet Holmgren, who was largely neutralized in Game 1 by San Antonio’s switching defensive scheme. If OKC can unlock Holmgren as a secondary creator in the pick-and-roll, San Antonio faces a choice it could not make effectively in Game 1: guard both Gilgeous-Alexander and Holmgren simultaneously. Jalen Williams, who returned from a hamstring absence in Game 1, is expected to play a more central offensive role in Game 2.

De’Aaron Fox remains out with the ankle sprain that kept him from Game 1. Dylan Harper, the rookie who posted 24 points, 11 rebounds, 6 assists, and 7 steals in his Conference Finals debut, will again start in his place.

The NBA set a record for Conference Finals viewership in Game 1 of the Western series Monday — 8.4 million viewers across NBC and Peacock. Tuesday’s Game 1 in the East has not yet posted final viewership numbers, but the combination of MSG, Brunson, and a 22-point comeback in the fourth quarter at one of the most-watched arenas in American sports will almost certainly push the number higher. Both series resume within 48 hours. The basketball, right now, is extraordinary.
