Knicks vs. Celtics odds to use with your FanDuel promo code

Boston has a six-point lead, having beaten New York by double digits four times last season. The Knicks want to show that they have moved closer to the Celtics' elite class with their big offseason moves.

Jalen Brunson confirmed he was a big player type in last season's playoffs when he averaged 32.4 points per game. This matchup could have a playoff feel, and Brunson can help the Knicks cover even if they lose.

Look forward to an interesting battle between three-point artists from the middle position. Al Horford and Karl-Anthony Towns ranked first and second, respectively, in field goal percentage at their position last season.

The Celtics will return most of their championship core for the opener. Jayson Tatum scored a game-high 35 points against New York last season.
