Karl-Anthony Towns Posts the Highest Single-Postseason Plus-Minus in NBA History

Karl-Anthony Towns finished the 2026 NBA postseason with a plus-minus of +258 – the highest single-postseason mark in league history. The New York Knicks center surpassed Stephen Curry‘s previously untouched +245 from the 2017 Golden State Warriors title run, a number that had stood as the gold standard of playoff dominance for nearly a decade.

The record was confirmed by the NBA’s official X account following the Knicks‘ championship run – a series that drew its largest viewership since 1998 and produced one of the most dominant postseason performances the league has ever tracked.

What a Plus-258 Actually Says About This Postseason

A historically high mark reflects consistent dominance over the course of six to seven weeks of basketball, not one or two blowout series. At +258, Towns cleared Curry‘s benchmark by 13 points while also finishing ahead of Knicks teammate Jalen Brunson, who posted +235 in the same run.

The 2026 Knicks posted an NBA playoff-record +14.9 average margin of victory to emphatically seal their first title in 53 years. Towns and Brunson were the engines behind the most lopsided championship run in postseason history.

What Towns Actually Did to Earn It

Towns averaged 24.2 points, 10.8 rebounds, 3.6 assists, and 1.4 blocks on 52 percent from the field and 41 percent from three across the 2026 postseason.

He logged multiple outings of +20 or better in each series, which reflects consistency rather than a handful of inflated outliers pulling the average up.

For comparison, his best single-postseason plus-minus with the Minnesota Timberwolves was +29 in 2022.

What Minnesota Could Never Make Possible

The Minnesota chapter of Towns‘ career produced two series wins in nine seasons. He was consistently one of the most skilled big men in the league – a legitimate two-way center who could shoot, pass, and defend – and it was never enough to matter when October became April.

The move to New York was framed by many as a chance for a larger market and a better supporting cast, but the underlying question was always whether Towns could hold up when the games counted most.

The 2026 postseason answered that plainly. The record belongs to him now, set in the building where Mitchell Robinson and the rest of the Knicks’ championship roster delivered the franchise its first title in decades.

Does the Record Settle the Debate, or Start a New One?

The honest counterargument is that plus-minus is a team stat wearing individual clothing. The 2026 Knicks were so dominant that Brunson was also so close to setting the record. It is debatable about how much of Towns‘ number reflects his individual impact versus the team’s collective destruction of every opponent they faced.

What the record cannot be dismissed as, however, is a fluke. Posting +258 requires sustained two-way production across four rounds. It requires staying healthy, staying effective, and staying on the floor in games that are already decided – which means playing well enough that coaches keep you out there.

The record is set. Whether it reframes how Towns is remembered long-term depends on whether the Knicks sustain this level – but one postseason like this is already more than most stars ever produce.
