Will Celtics Run It Back in 2025?

Almost every significant contributor on the 2023-24 Celtics team is under contract for the 2024-25 season. The most-notable (potential) free agent is Sam Hauser (9.0 PPG, 3.5 RPG, 42.4 3P%), whom the C’s can pick up with a $2.1 million team option.

Boston’s only impending UFA’s are Luke Kornet (5.3 PPG, 4.1 RPG), Xavier Tillman (4.0 PPG, 2.7 RPG), and Sviatoslav Mykhailiuk (4.0 PPG, 1.2 RPG).

So if GM Brad Stevens is content with his squad that posted a league-best +11.7 Net Rating in the regular season (4.4 higher than any other team) and a league-best +8.0 Net Rating in the playoffs (1.6 higher than any other team), he can basically take the offseason off.

Are the Mavericks Poised for Another Deep Run?

West-champion Dallas is in a similar position. Their only notable impending UFA is Derrick Jones Jr (9.0, 3.6 RPG). But the Mavs weren’t exactly the juggernaut that the Celtics were at any point this season. They managed just the 15th-best Net Rating in the regular season (+2.1) and fifth-best in the playoffs (+3.6) despite winning 12 of their first 17 games in the postseason.

While Luka Doncic has an argument for best player in the league, his supporting cast scarcely looked like championship-caliber teammates.

In the West, OKC appears to be a team built to challenge for years to come. OKC had the second-youngest roster in the league this year, yet still earned the #1 seed in the West and posted the second-best Net Rating in the NBA behind Boston (+7.3).

Gordon Hayward (5.3 PPG, 2.5 RPG) is a UFA along with Bismack Biyombo and Mike Muscala, who combined to average just 2.9 PPG in only 26 games. OKC has a $2.1 million club option on Isiah Joe (8.2 PPG, 2.4 RPG) and a $2 million club option on Aaron Wiggins (6.9 PPG, 2.4 RPG).
