After Sunday’s Celtics win in Orlando, Jayson Tatum shared that his new 3-point celebration was inspired by rookie teammate Baylor Scheierman. Two nights later, Scheierman explained the story behind that inspiration. Speaking with the Herald ahead of Celtics-Magic Game 5 at TD Garden, Boston’s first-round draft pick said the celebration – reaching his arms above his head and grabbing his right wrist – was a spur-of-the-moment reaction that Tatum spotted and chose to adopt. “Obviously he’s got a hurt wrist and was out Game 2 and came back, and obviously it’s talked about a lot,” Scheierman said, referring to the bone bruise Tatum suffered in Game 1 of the first-round playoff series. “It just honestly came to mind when he hit a three (in Game 3). I just grabbed the wrist, put up a 3-point celebration. I think he kind of saw it out of the corner of his eye, looked over and kind of liked it. He told me coming into the timeout, he was like, ‘Yo, rook, that’s tough.’ So he just kept on doing it.” Tatum’s wrist injury hasn’t fully healed – he’s played with it taped since returning to action last Friday – but it didn’t hinder his scoring ability during the Celtics’ two games in Orlando. He racked up 36 points in a Game 3 loss, then dropped 37 with 14 rebounds in Game 4, scoring 16 points in the fourth quarter as Boston pulled away to take a 3-1 series lead. “It’s pretty remarkable,” Scheierman said. “Obviously, he’s playing through it, and that’s just who he is. He wants to be out there every single game playing with everybody, and he’s the ultimate competitor. Obviously, what he was able to do (in the) two games down there in Orlando was special, and I’m just looking forward to continuing watching him throughout this playoffs.” Barring a slew of injuries above him on the depth chart, watching likely will be Scheierman’s primary job this postseason. The 24-year-old Creighton product saw consistent playing time late in the regular season but is not part of head coach Joe Mazzulla’s playoff rotation. Despite his minor role, Scheierman said he’s having “a lot of fun” as he experiences NBA basketball for the first time. “Just the atmosphere, obviously, and just the heightened, I guess, intensity, I’d say,” he said. “Obviously, the game is played with a lot more physicality than the regular season; I think that’s probably the biggest difference. But other than that, it’s just basketball at the end of the day, so it’s a lot of fun to be a part of.” Holiday out; Brown in Celtics starter Jrue Holiday missed his third consecutive game Tuesday as he recovers from a hamstring strain. In each of his last two DNPs, the team bypassed the “questionable” designation, ruling Holiday out the day before Game 4 and Game 5. Asked whether the veteran guard could be looking at a longer-term absence, Mazzulla said he still is considered “day to day.” “Jrue’s doing everything he can to come back,” Mazzulla said. “He’s day to day, and he’s doing everything he can to put himself in a position to be a little bit better the next day.” Magic head coach Jamahl Mosley said the Celtics look “majorly different” when Holiday is not in the lineup. Boston entered Tuesday with a 15-7 record this season when the 34-year-old sits. “He adds so many small, intangible things to this team,” Mosely said, echoing comments Mazzulla made over the weekend. “One, his toughness, his resolve on the court. He never gets rattled. He blows up all the things you’re trying to run offensively, defensively. He finds different ways. And the great part, talking about the coaching battle, it’s just been Payton Pritchard stepping into that role. He’s moving into the (spot where) he’s going to pick up full-court, he’s going to change the game. And now they’re rolling off of (Al) Horford in situations, so those guys are just taking on that role that Jrue has with him being out.” Jaylen Brown, who’s dealt with a lingering knee injury since before the All-Star break, was upgraded from questionable to available before the game. “He’s taking care of himself, doing everything he can,” Mazzulla said. “I think that’s the thing about both those guys, really. They’re doing everything they can to put themselves in a position to play. Jaylen’s been doing that. He’s great for us. He’s going to keep doing that.” Mosley enjoying the ‘chess match’ The Celtics carried a 3-1 series lead into Game 5, but three of the first four contests were decided by single digits, and the muck-it-up Magic successfully turned each into a physical, low-scoring slog. Neither team reached 110 points in any of the first four games, and Orlando succeeded in limiting the central weapon of Boston’s offense: 3-point shooting. The Celtics had their lowest and second-lowest 3-point attempt totals of the season in Games 3 and 4, respectively. Six of their nine lowest this season have come against the Magic, who allowed the fewest threes of any team in the NBA. “You have to stick to who you are,” Mosley said. “You see so many teams that try to adjust to something different because they’re chasing something else. You can’t do that. If you have an identity and it’s worked for you, you have to stick to that. … You have to do that because you’re establishing something bigger than just this moment.” Mosely, who’s in his fourth season as Orlando’s head coach, said he’s thoroughly enjoying matching wits with Mazzulla. “I absolutely love it,” he said. “Joe is an incredible coach. He does a great job of putting his guys in the right spaces, after timeouts, finding different situations to put guys in to have them constantly thinking throughout the game. This is the part of coach that you love – that chess match of trying to figure out what you can do without overthinking it and putting yourself in a situation where you have to worry about not doing what you’re capable of doing because you’re chasing something that they’re doing.” Off the rim In a recent interview with GQ Sports, Jayson Tatum called Mazzulla “the best coach in the NBA – even though he’ll never admit that. He always tells me that he loves me. He’ll say it on practice days or in the middle of a game during a timeout. It’ll be the third quarter of a playoff game, a very intense atmosphere, and he’ll say, ‘Just want you to know I love you, man.’” Tatum also said he and his Celtics teammates “love to watch (Mazzulla’s) press conferences,” which are known for producing absurd quotes and deadpan one-liners. … Yet another format change could be coming to the NBA All-Star Game. After the league’s new mini-tournament setup flopped this year, commissioner Adam Silver and his lieutenants are considering adding an international flavor to All-Star 2026. Silver told The Athletic that the NBA is “discussing concepts with the players’ association that focus on NBA players representing their countries or regions instead of the more traditional formats that we’ve used in the past.” The NHL’s decision to replace its 2025 All-Star Game with the best-on-best Four Nations Face-Off was a smashing success that drew monster ratings. Next year’s NBA All-Star Game is set to be held during the Winter Olympics and air on the same network (NBC) that carries the Games.
