It’s late March when Jordan Walsh plops down in a director’s chair in a theater where we are taping interviews with the members of the Celtics. It’s one day before Walsh, who at times earlier in the 2025-26 season felt like he was finally on the path to consistent playing time, will log his sixth consecutive DNP.
Walsh started 20 consecutive games from Nov. 12 to Jan. 1, raising eyebrows around the league with his relentless energy and defensive potential. But his playing time slowly evaporated, culminating with this late-March dry spell.
As Walsh waited his turn in our chair, he was punching away at his phone. On the other end was former Celtics forward Xavier Tillman, who played sparingly here over two-plus seasons but never let a lack of floor time dictate his attitude and approach. Tillman was ready whenever called upon, including in key spots during the team’s 2024 NBA Finals triumph over the Dallas Mavericks.
Walsh learned a lot about what it means to be an elite teammate and a true professional by watching the way Tillman carried himself in Boston. Tillman got dealt to Charlotte in a series of cost-cutting moves at the February trade deadline.
But Walsh continues to lean on Tillman’s wisdom in the aftermath.
“We talk all the time, even if it’s not basketball-related,” said Walsh. “Sometimes it’s just me sending him Instagram reels of funny stuff and him sending something back. Or like food — we talk about food a lot, too. It’s just random stuff but I think that’s a big part, too.
“[Tillman is] a guy who’s removed from our organization and is technically competing against us now, [but he’s] still looking out for the best for me and trying to give his help as a vet. I think it’s huge.”
How ironic, then, that just a couple days after our chat, Walsh returned to the lineup, making a spot start against Tillman’s Hornets. In fact, Walsh made 10 straight appearances to close out the regular season (including five starts) while reaffirming his ability to help Boston with his defensive tenacity and energetic rebounding.
Being ready for the moment helped Walsh state a case for postseason playing time. He’s appeared in all five games for Boston in these playoffs, often being an early sub tasked with chasing All-Star guard Tyrese Maxey through a never-ending gauntlet of screens. But Walsh dutifully fights through every Andre Drummond and Joel Embiid pick as if staying attached to Maxey is the key to his survival.
Entering Game 6 of an Eastern Conference first-round series against the Philadelphia 76ers, and with the Celtics facing a second chance to close out an Atlantic Division rival Thursday night, Walsh leads Boston’s playoff regulars in defensive field goal percentage differential, holding his opponents to 9.5 percent below expected output.
Opponents are shooting 36.4 percent when Walsh is the primary defender, per NBA tracking. Chasing Maxey is a thankless and nearly impossible task. Maxey has generated 15 points on 6-of-13 shooting with two turnovers and a blocked shot while defended by Walsh. All other Sixers players are 2-of-9 shooting with four points when Walsh is the primary defender.
In December, players like Austin Reaves were raving about how Walsh could be “one of the best defenders in the league for many years to come.” After limited playing time in his first two seasons in green, Walsh finally seemed to be carving out a role.
But Walsh stayed engaged even when his playing time evaporated, as head coach Joe Mazzulla cycled through all of Boston’s young wings at various points during the 2025-26 season.
“I think a big part of it is understanding that, if you’re not playing, you’re still holding onto the rope,” said Walsh. “You’re still a kind of support beacon of hope, almost, you could say, for the team and for guys. At no point are you left out. At least in this organization, there’s never a point where I felt like I was left out, or not in consideration or not being thought of or protected.
“So just knowing that, at every point, you’re still a part of the machine, whether your cog is [big or small], you’re still a part of it and, with you, it moves the machine forward.”
And when his playing time became sparse, Walsh leaned on Tillman.
Hearing his point of view … it helps you stay sane. … It keeps you here, keeps you focused.

“Obviously it’s big because, like I told you, I never felt like I was given up on. A guy I talked to a lot is Xavier,” said Walsh. “He’s been in this situation. Obviously, it’s a little bit different, but he was here for two years, didn’t play most of the year, goes in the Finals against the Mavs, hits a really big shot.
“So hearing his point of view, and I’m talking to Al [Horford], talking to guys that are here, [Jaylen Brown] — JB and me [are] always going back and forth. It’s a big part of it. It helps you stay sane, you don’t lose yourself in the, ‘I’m not playing,’ or ‘I am playing,’ and these guys still support you. So it keeps you here, keeps you focused.”
The Celtics are outscoring the Sixers by 23.5 points per 100 possessions with Walsh on the floor this postseason. Boston’s defensive rating is 8.4 points per 100 possessions better during Walsh’s court time, with the team posting a 103.8 defensive rating in his 65 minutes.
Celtics president of basketball operations Brad Stevens, who selected Walsh 38th overall in the 2023 NBA Draft, knew Walsh would maximize his opportunities.
“I think Jordan has always been probably as talented a young player, physically — especially on the defensive end — that we’ve had,” said Stevens. “But he just got thrust into a team that nobody was going to play on. So it’s been good to see him take advantage of these opportunities. But you could kind of see that coming over time.”
Walsh has produced multiple highlight-worthy hustle sequences in the postseason, including one scramble for an offensive rebound in Philadelphia that ignited the entire Celtics bench.
It’s not easy to come off the bench and chase Maxey, but Walsh does what he’s asked. The Celtics have outscored the Sixers by 45 points in Walsh’s floor time in the three wins.
Tillman’s time in Boston might have ended in February, but his impact lives on in Boston through Walsh.
