The New York Knicks will face the Boston Celtics on October 23, 2026, at 7:00 PM ET.
Knicks vs. Celtics Props & Analysis
- Jalen Brunson (New York Knicks): 25.5 Points
- Karl-Anthony Towns (New York Knicks): 11.5 Rebounds
- OG Anunoby (New York Knicks): 16.5 Points
- Josh Hart (New York Knicks): 3.5 Assists

When analyzing the early-season numbers, a few lines stand out as potential value targets. For the Boston Celtics, Paul George opened his season with a massive 38-point performance across 31 minutes. His consensus line for total points is set at 17.5, making a projection for him to exceed this total a highly appealing option given his current form. Meanwhile, Jayson Tatum offers an interesting dilemma; his points line is set at a lofty 26.5, but he only managed 13 points in his first outing, offsetting that lower scoring output by racking up 11 assists.
On the New York Knicks’ side, Karl-Anthony Towns pulled down 12 rebounds in his regular-season debut. With his consensus rebounding line sitting at 11.5, projecting him to surpass this mark aligns well with his early production on the glass. Point guard Jalen Brunson scored 21 points in his first appearance, falling slightly short of his listed 25.5-point total. Daily fantasy players will need to weigh whether he is in line for increased shooting volume tonight against the Boston Celtics.
