Concerned about the Celtics?

I get that it's the regular season and the Celtics may just be taking it easy, but is anyone else slightly concerned about possible regression and the league being better this year than last year?

Shooting continues to be a big concern this year, as they are shooting poorly from three:

• Last year: 38.8% from 3P (2nd)
• This year: 36.2% from 3P (15th)

Player Shooting Regression (2023/24 - 2024/25):

• Jayson Tatum: .376 → .359
• Jaylen Brown: .354 → .319
• Derrick White: .396 → .379
• Jrue Holiday: .429 → .343
• Al Horford: .419 → .343
• Sam Hauser: .424 → .376
• Kristaps Porzingis: .375 → .347

There’s been major regression across the board for the Celtics' main contributors (outside of Pritchard).

Across-the-board metrics:

• Offensive rating is down 3 points, and defensive rating is down 1 point.
• Defensive rebounds: 1st in 2023/24, 8th in 2024/25.

Since December 7th, the Celtics have a record of 8-7. Per Cameron Tabatable, during that span, the Celtics rank 5th in offense and 4th in defense. However, in 4th quarters during that same span, they are 8th in offense and 25th in defense.

Despite some of these numbers, there are some good counter-arguments that suggest they might just be taking the regular season slowly.

• During Kevin Durant's first year with the Warriors, they went 67-15 and won the finals. The very next season, they went 58-24 and won the finals again.
• The Celtics continue to remain on a 60-win pace with nearly identical offensive and defensive rankings across the NBA.
• Kristaps Porzingis has only played 16 games, and the Celtics are 9-7 in those games, losing to teams like SAC, OKC, MEM, and CLE.
• The starting five of White, Holiday, Tatum, Brown, and Porzingis have logged just 116 total minutes together.

As a Celtics fan, what's your concern on a scale of 1 to 10?
