New York Knicks vs Miami Heat Predictions, Betting Odds and Best Bets for Sunday, December 21 

Garima Ranawat

The New York Knicks will welcome the Miami Heat for an NBA 2025-26 regular-season clash on Sunday, December 21. This will be the fourth time both teams will be up against each other in the current NBA season. In the previous three games, the Heat dominated the rivals twice, while New York handed them an eight-point defeat once to take the tally 2-1. Talking about the upcoming game, the Knicks are coming off a nine-point loss to the Philadelphia 76ers. On the other hand, the Heat are coming off a 13-point loss to the Boston Celtics in their most-recent game.

Recommended Bet and Odds 

Recommended Bet FanDuel BetMGM
Norman Powell O 24.5 Points -110

Analysis and Rationale 

Norman Powell is leading the Miami Heat with an average of 24.1 points through 23 games in the NBA 2025-26 season. He is shooting 48.7% from the field and 41.1% from the three-point range. In addition to it, he is also contributing 3.8 rebounds and 2.5 assists per game. 

In the most-recent game against the Celtics, he dropped 18 points and was shooting 33.3% from the field and just 9.1% from the three-point range. In his last five appearances for the Heat, he dropped 20+ points thrice, which included a 24-point show against the Brooklyn Nets. 

Though the Knicks have home-court advantage over the Heat, and they are in better form, the latter have a better defensive rating. Considering this, we think Powell is expected to score over 25 points on Sunday. 

New York Knicks vs Miami Heat Predictions

The New York Knicks got off to a decent start of the season. And, while they have had a few struggles, the Knicks were in red-hot form recently. Their seven-game winning streak recently came to a halt owing to their nine-point loss to the Philadelphia 76ers. The Knicks have won eight of their last ten games, and are absolutely lethal at home, owning a 13-2 record.

They are scoring 120.2 points per game, while allowing 112.4 points. The Knicks have the second-best offensive rating of 121.3, and have a mid-rack defensive rating of 113.6. While they have recently gotten a setback in the form of their recent loss, the Knicks are in a momentum, and considering their home-court advantage, they hold an upper hand in the upcoming clash against the Miami Heat. 

The Miami Heat, on the other hand, are having a decent season thus far, owning a 15-13 win-loss record, grabbing seventh seed in the standings. However, in the last ten games, they have been able to record victory in only three games. While they hold advantage in home games, their on-road record highlights their woes and efficiency struggles. 

They are scoring 120.0 points per game, while allowing 117.3 points to their opponents. This shows that while the Florida-based franchise has an efficient offense, they are in dire need of improving their defense. Their offensive rating of 114.0 gives them 15th spot in the league, while a defensive rating of 111.7 has given them the fourth spot. 

There is no doubt that the Heat are 2-1 dominant over the Knicks, but as per the recent form and momentum, we expect the Knicks to record a victory over the Heat and level the tally. 

Predictions: New York Knicks to win.
