The Boston Celtics have a real shot to own the glass this season.
That case starts with the return of Jayson Tatum, the arrival of Mitchell Robinson, and the continued growth of Neemias Queta. Add in the development of wings like Baylor Scheierman and Hugo Gonzalez, and the Celtics suddenly have a roster built to chase rebounds on both ends.
That matters for Boston in a big way. Rebounding is the final piece of defense - all the pressure in the world doesn’t matter if the possession ends with an opponent’s putback.
It also fits the way Joe Mazzulla has wanted this team to play for years. The Celtics live on jump shots, so crashing the offensive boards becomes a kind of pressure release valve when the rim isn’t there.
The numbers from last season already put Boston near the top. They finished fifth in offensive rebounding percentage at 33.6%, fifth in defensive rebounding percentage at 71%, and third overall at 52.5%. They also led the league at 46.9 rebounds per game.
The question is how much higher they can climb. The answer looks like: quite a bit.
A good template comes from the Celtics team of three seasons ago. That group finished with the league’s second-best defensive rating and held opponents to the second-lowest field goal percentage in the NBA.
They were near the bottom in forcing turnovers because they weren’t hunting steals. Instead, they stayed home, contested shots, and cleaned up the misses.
They also ranked third in overall contested shots.
That approach lines up neatly with what this roster can do now. Boston has size, rebounders, and enough discipline to challenge shots without giving away free throws. In that 2024 season, the Celtics allowed the fewest free throw attempts in the league, and that should remain the goal.
Start with defense. The Celtics allowed 86.8 field goal attempts per game last season, sixth-fewest in the NBA.
Brooklyn allowed the fewest at 84.7. Boston probably won’t play fast this year, so staying in that same range makes sense.
Round that to 87 shots a game, and if opponents shoot 44% - close to last season’s 44.2%, which ranked second in the league - that leaves 49 missed shots.
From there, the math gets interesting. Boston grabbed 71% of those misses last season, and there’s reason to think that number can tick up with Tatum and Robinson in the mix.
Tatum pulled in nearly 17% of the defensive rebounds in his return last season, though he had been just below 13% before that. Robinson grabbed 26% last season, but he’s usually closer to 21%.
They’d be stepping into spots that included Jaylen Brown’s 11.1% and Luka Garza’s 12% at least part of the time, so some increase is reasonable. The only catch is that rebounds can’t be shared in the moment - Tatum, Robinson, and Queta can all help, but only one of them can actually finish the play.
If Boston gets to 72% on the defensive glass, that would push the team closer to 35 defensive rebounds per game. Match San Antonio’s NBA-best 72.4%, and the Celtics could get to 35.5.
The offensive side is a little trickier. Boston shot 46.7% from the field last season, which ranked 16th in the NBA.
Their volume of threes will always drag that number down, but they can do better than that. If they shoot better, they’ll create fewer offensive rebound chances overall.
Still, Robinson changes the picture. Luka Garza was solid last season, grabbing 15.7% of available offensive rebounds and averaging 2.3 per game.
Robinson was at 23.9% and 4.2 per game. That’s a major jump in pure offensive glass work.
Tatum, though, doesn’t bring much there. His career offensive rebounding percentage is 2.8%.
Robinson had 252 offensive rebounds last season, more than Tatum has combined since the 2022-23 season. Brown wasn’t exactly living on the offensive boards either, but he did average one more per game than Tatum, which trims some of Robinson’s edge.
Even so, Boston should be able to move up a bit from last season’s 33.6% offensive rebounding rate. If that climbs to 35%, right around the Detroit Pistons, the Celtics could land at about 13.5 offensive rebounds per game. That would move them from seven in per-game average to roughly third, using last season’s numbers.
Put it together and Boston could end up around 49 rebounds per game. That would have led the league in every season since the 2021-22 Memphis Grizzlies, who averaged 49.2.
So yes, the Celtics have a legitimate path to becoming the NBA’s best rebounding team. And that’s before even accounting for more growth from Queta or the younger wings. There are only so many boards to go around, but Boston has the size and the personnel to take most of them this season.

Celtics Suddenly Have A Frontcourt Decision Fans Will Want To Watch
Mitchell Robinsons arrival gives Boston a new wrinkle in the frontcourt after the Celtics added the former Knicks big man fresh off a championship season in New York. For a team that has spent plenty of time sorting out how its centers fit together, the move creates another layer to a rotation already built around size, rim protection and matchup-specific choices.
Neemias Queta seemed to welcome the competition, saying he was positive about Robinson joining the team and leaving the rotation call to Joe Mazzulla. Queta also made the case that he and Robinson bring different strengths, which could matter depending on the opponent and the game plan, and that is exactly why this is worth watching once the season starts to sort itself out.

Celtics May Have Found The Perfect Veteran For Payton Pritchard
Mike Conleys arrival in Boston looks less like a splashy roster move and more like a targeted effort to steady the Celtics guard room. The veteran point guard signed a one-year contract and has already begun working closely with Payton Pritchard, offering the kind of day-to-day guidance that can matter just as much as minutes in the rotation. With Jaylen Brown traded, the Celtics have every reason to make sure their backcourt keeps developing in the right direction.
Conley has been clear that he may not have a major on-court role, but he can still help in ways that show up over the course of a season. For a team leaning on Pritchard to grow into a bigger piece, that makes Conley a useful addition beyond the box score. His early impression is that of a pro who understands the assignment, and Boston will be hoping the mentorship pays off in the place it matters most, on the floor. [Read more 🡒]
Celtics Begin Explaining Their Post Jaylen Brown Overhaul
The Celtics spent the start of their offseason makeover laying out the logic behind a roster that looks a lot different after the trade sending Jaylen Brown to Philadelphia brought Paul George and multiple draft picks back to Boston. At a press conference introducing George and Mike Conley Jr., the team also noted Mitchell Robinson was absent because of a personal matter, underscoring just how much change has already swept through a group that has also added Robinson and Conley in free agency.
Beyond the headline moves, Boston has continued to work on the edges of the roster, locking in contract extensions for Jordan Walsh and Neemias Queta. The bigger story, though, is how the Celtics intend to sell this new era after moving one of the franchises defining players, and the first public step came with George and Conley front and center while the rest of the plan remains in motion.
