Both teams made significant changes during the offseason. Boston traded F Jaylen Brown to Philadelphia in exchange for F Paul George, giving F Jayson Tatum a new All-Star running mate, while adding veteran PG Mike Conley and C Mitchell Robinson — who led the NBA in offensive rebounds last year — to bolster its depth. 

Detroit, meanwhile, added PF John Collins and G Isaiah Joe but lost F Tobias Harris, SG Caris LeVert, and PF/C Isaiah Stewart. The Pistons also secured C Jalen Duren's long-term future, keeping a key piece of their young core alongside PG Cade Cunningham as they look to build on last season's 60-win campaign.

Despite the new faces, head coach Joe Mazzulla’s overall philosophy will likely remain the same for Boston: shoot the ball from deep. The Celtics posted a 120.8 offensive rating last season, ranking second in the NBA, while attempting 46.7% of their field goals from beyond the arc. Defensively, they were also elite, posting an 111.7 defensive rating (fourth).

Detroit finished last year with a 117.3 offensive rating (ninth) and a 108.9 defensive rating (second). The Pistons' +8.4 net rating was tied for second-best in the NBA with the Spurs, reflecting their ability to win games on either side of the court.

Here are the key stats behind our Celtics vs. Pistons prediction on Tuesday afternoon, including a pick for the point spread on PrizePicks.

Unless otherwise noted, data used in this article is from Basketball-Reference, NBA.com, and StatMuse.

• These teams are incredibly evenly matched, but a couple of trends point to Detroit snagging a home win.
• Mitchell Robinson's addition should help the Celtics secure a ton on the boards, but they are running into one of the few teams in the league that can match them on the glass. Last season, these teams were tied for third in overall rebounding percentage (52.5%).
• The Pistons did have a slight edge, though, thanks to a 35.4% offensive rebounding rate compared to the Celtics' 33.6%.
• The Celtics' offensive philosophy remains to relentlessly shoot 3-pointers. They averaged 47.0 3-pointers per game in the preseason (second-most).
• That plays into a past strength for the Pistons, who held opponents to just 34.5% from deep last season — the league's lowest allowed 3-point percentage.
• The Pistons have the edge in recent head-to-head results. Detroit won three of four meetings last season, holding Boston to 109.5 points per game across those contests.

Celtics vs. Pistons Picks, Player Stats for Opening Day on PrizePicks – 10/20/26

Here are two Celtics vs. Pistons player picks to consider on PrizePicks today, featuring Jayson Tatum and Cade Cunningham.

Celtics F Jayson Tatum vs. Pistons: 41.5 Pts + Rebs + Asts

• Tatum's workload could skyrocket without Jaylen Brown. In three games minus Brown last season, Tatum posted a massive 38.3% usage rate, averaging 27.3 points, 10 rebounds, and 7.0 assists per game (44.3 PRA).
• The expected increase to playmaking opportunities makes this projection especially encouraging. Tatum averaged 7.0 assists in those three games without Brown, compared to 4.9 assists when he was on the court. With more possessions running through Tatum, his assist upside gives him another path to clearing the number even if his shot isn't falling.
• He also took on a heavier scoring load on the road last season, averaging 23.0 points per game away from home, up from 20.5 in Boston.
• Tatum should see a lot of F Ausar Thompson and PG Cade Cunningham defensively today, but that doesn’t draw much concern. Thompson finished last season with a 107.2 defensive rating (13th on the Pistons) while Cunningham’s 109.0 defensive rating ranked 17th on the team.

Add Jayson Tatum to your PrizePicks lineup now.

Pistons G Cade Cunningham vs. Celtics: 38.5 Pts + Rebs + Asts

• This number could be too low for a guy who will be Detroit's offensive hub, owning one of the sport's higher usage rates.
• He posted a 29.8% usage rate last season, the 12th-highest among eligible players, and that number may tick over 30.0% this season.
• His 45.2% assist percentage ranked among the league's elite, highlighting how much of Detroit's offense runs through him.
• Cunningham averaged 39.3 PRA last season, +0.8 above this current projection.
• With this game essentially a pick 'em, there's no concern about Cunningham missing any time due to a blowout, as we should get four competitive quarters of basketball this afternoon.

Add Cade Cunningham to your PrizePicks lineup now.
