Knicks vs Celtics Full Game Pricing


Updated October 23, 2026

The defending NBA champion New York Knicks visit the Boston Celtics on Friday, October 23, 2026, with both Eastern Conference contenders looking for their first victory of the season. New York dropped its opener 106-100 to Philadelphia, while Boston surrendered a 22-point lead in a 121-113 loss to Detroit. Friday's 7 p.m. ET contest at TD Garden features several intriguing player prop opportunities, particularly in the rebounding market, as Mitchell Robinson faces his former team as a member of the Celtics.
Take Towns' Over
At the quoted Polymarket price of 51¢, a Yes position on Towns recording 12+ rebounds carries an implied probability of 51%. Our estimated 56% probability creates a 5% advantage, making this an appealing position at the stated entry price. The model's fair value is approximately 56¢, although the recommended entry ceiling is 53¢ to retain a meaningful cushion against uncertainty.
Why Take the Over
The pricing discrepancy comes primarily from Towns' ability to accumulate rebounds without requiring unusually heavy minutes. His opening-night performance demonstrated that even an abbreviated appearance can produce the necessary volume. The Celtics remain capable of controlling the boards, particularly with Robinson and Neemias Queta available, but their first outing exposed weaknesses in rebounding execution.

Why Our Model Sees Value:

“The 51¢ price appears to place too much weight on the difficulty of reaching 12 rebounds against Boston without fully accounting for Towns' exceptional rebounding production, his potential for increased playing time, and the Celtics' early frontcourt concerns.”
Towns enters Friday with an impressive statistical record. During the 2025-26 regular season, he averaged 11.9 rebounds across 75 games, ranking second in the NBA. His production included 8.7 defensive rebounds and 3.1 offensive rebounds per game in approximately 31 minutes.
His advanced rebounding numbers are especially encouraging. Towns recorded a 21.4% total rebound rate and a 31.7% defensive rebound rate last season, illustrating his ability to secure a substantial share of available opportunities while on the floor.
That production carried into New York's opener. Against a Philadelphia frontcourt featuring Joel Embiid, Towns finished with 19 points and 12 rebounds, including 3 offensive boards and 9 defensive rebounds. He accomplished that despite playing only 24 minutes because of early foul trouble.
The Celtics have undergone significant personnel changes, with Robinson replacing some of the interior presence previously supplied by their established rotation. That lack of continuity can have a huge impact on the outcome of Knicks vs Celtics predictions on Friday night.
Robinson brings size, shot-blocking ability, and offensive rebounding experience. However, his first regular-season appearance with Boston produced just 3 rebounds across approximately 18 minutes. Queta added 4 rebounds in 22 minutes.
Boston consequently lost the rebounding battle 49-39 against Detroit, even though the Celtics ranked among the NBA's stronger rebounding teams last season. That opening performance does not prove Boston will struggle on the glass throughout the season. Nevertheless, it raises questions about how effectively the new center rotation can control the defensive boards.
Towns should also be able to avoid foul trouble against the Celtics in this contest. Queta and Robinson are not going to drive at Towns, reducing the likelihood of him picking up defensive fouls. He could still rack up offensive fouls, but not enough to take him out of the game.
Boston's offensive approach could influence Towns' final total. Paul George scored 38 points in his Celtics debut, while Jayson Tatum struggled through a 6-for-23 shooting performance.
Boston attempted 42 three-pointers against Detroit, converting 17. That perimeter volume can create rebounding opportunities, although longer misses also allow opposing guards and wings to collect boards outside the paint.
New York's defensive personnel should also play a role. OG Anunoby, Mikal Bridges, and Josh Hart offer perimeter size and activity, potentially allowing Towns to concentrate more heavily on securing defensive rebounds.
The risk is that Boston shoots more efficiently than it did in its opener, reducing available defensive rebounds. A particularly strong performance from Robinson on the offensive glass could also keep Towns occupied with boxing out rather than collecting the ball himself. But KAT should be able to reach 12 boards thanks to the favorable matchup he will see for most of this game against slower bigs.
