A season-long look inside the on- and off-the-court life of Jayson Tatum hit Netflix on Wednesday.

The Boston Celtics centerpiece is one of the stars of “Starting 5,” a new docuseries from the streaming service that also features LeBron James, Jimmy Butler, Anthony Edwards and Domantas Sabonis.

After watching all 10 episodes, here are seven Tatum-related takeaways:

1. Weight of championship expectations

The series culminates, of course, in Tatum winning his first NBA title. The first nine episodes drive home the pressure he felt to get there.

“If you want to succeed here, you either hang your championship [banner], or you don’t,” Tatum said.

“I’ve had a lot of success here wearing this uniform, but we haven’t achieved the ultimate goal. I think to be in the conversation with the greats, one of the best Celtics, it’s kind of crazy. But obviously, to be in that conversation, you have to win championships.”

Asked what he’d give to be an NBA champion, Tatum said he’d “cut off one of my fingers to win a championship if that’s what it meant.”

And how it felt to finally win it all?

“Man, this is what I dream about,” Tatum said. “This is what I’ve been dying to accomplish, and it’s here. … Everything that I had to endure and listen to, I just felt like the weight of the world was off my shoulders in that moment.”

Tatum said there’s still more he wants to accomplish in his NBA career — a point he emphasized last month at Celtics media day. More records. More championships

“But when you really sit back and take a step back and look at it,” he added, “it’s like, I am — I’m one of the best players to ever play this game. I’ve done things that only the best of the best have ever done.”

2. Under the microscope

Tatum expresses his appreciation for the Boston fanbase (“by far the best fans in the NBA”) multiple times over the course of the series. But he admitted the added scrutiny he faces from the media — locally and nationally — can be difficult to deal with.

“Being one of the best players and being on Boston, there’s an expectation that comes with that,” he said. “Whether you turn on the TV and watch it or not, you’re always going to hear it. Those clips, those comments are always there.”

“We’re expected to win every single night, and when we lose, the [expletive] world is ending and everybody is on TV talking about us and how we’re not equipped to win a championship, how I can’t lead a team.”

Tatum added: “Sports media is tough. When we lose, it’s my fault. It’s hard to explain that or have other guys on the team understand. Like, nobody can really prepare you for how to deal with that.”

Asked about the criticism Tatum “has to deal with,” Celtics coach Joe Mazzulla quickly corrected the interviewer.

“Gets to deal with,” Mazzulla said. “He gets to deal with it. It’s the ultimate compliment. And that’s what we walk about. It’s like, this is what you asked for. You asked to be one of the best players in the NBA on the best team in the NBA with the opportunity to be an icon in the league for a long, long time. This is what you asked for.”

3. Best player controversy

Tatum also called out what he called the “slightly disrespectful takes” about him that flooded sports talk shows during the lead-up to the NBA Finals.

“It’s just Jayson Tatum, Jayson Tatum, Jayson Tatum, every day,” he said. “But I guess it felt good to be the underdog. First time in a while. So I was just ready to play basketball.”

One such take came from Dallas Mavericks head coach Jason Kidd, who famously declared during the Finals that Jaylen Brown, not Tatum, was Boston’s best player.

Tatum’s take on that: “I know I need JB. If I have to take less shots so that other guys can get more touches and other guys can get in a rhythm and we get over the hump and win the championship, that’s more important than me going out there trying to get 32 points a game.”

Brown was voted the MVP of the Eastern Conference finals and NBA Finals, but Tatum led Boston in points, assists and rebounds during its playoff run.

4. An early test

Tatum’s personal skills coach, Drew Hanlen, has been working with the Celtics star since Tatum was a freshman at Chaminade High School in Greater St. Louis. Hanlen initially was hesitant to train a player so young but said he’d take Tatum on if he could make it through his first workout without quitting.

“I got a call from Brandy [Cole-Barnes, Tatum’s mother], and she said, ‘Man, Jayson said that was the hardest workout he’s ever been through, but he said something really cool that I thought you’d be proud of,’” Hanlen recalled. “He said: ‘Momma, they were going to have to carry me off the court before I gave up.’ And that’s when I knew that he really had something … that was really going to allow him to take his game to a special level.”

The two still work together more than a decade later. Tatum recently shouted out Hanlen for helping him fix a few mechanical issues in his jump shot ahead of Celtics training camp.

5. Christmas jitters

Tatum said he felt off mentally during the Celtics’ Christmas Day road game against the Lakers because travel issues delayed his mother and son’s arrival in Los Angeles. They didn’t make it to the arena in time for tipoff.

“And them walking in just kind of gave me some more life, some energy,” Tatum said.

He wound up finishing with 25 points, eight rebounds and seven assists as Boston cruised to a 126-115 win.

Tatum’s relationship with his son, 6-year-old Deuce, is frequently spotlighted in the show.

“[He’s] the most famous person in Boston,” Tatum joked. “The biggest personality. My best friend. My mini-me.”

It’s Deuce who breaks the news to his dad that Tatum was chosen as the cover athlete for the “NBA 2K25” video game. Tatum replied, “Oh, [expletive]!” before tearing up.

6. “An a–hole type of Jayson”

Both of Tatum’s parents are featured in the show. His father, Justin, groomed him to be a basketball player since birth, with an intense approach that caused conflict between the two.

“I said, ‘Hey, I don’t really know what fatherhood is, but I know that I play a sport,’” said Justin Tatum, who was 18 when Jayson was born. “I was like, ‘Hey, this ball is going to bond us together.’ I was like, ‘I’m not just going to teach you how to grab a rebound or dunk the ball. I’m going to teach you everything. And how I’m going to teach you, you might not like it.’”

Asked during the East finals whether there was “another level to unlock” for his son, the elder Tatum replied: “Yeah, an a–hole type of Jayson that has not been displayed yet. … I think that’s what critics, people, even myself at times, want to see from him. I just think that level of competitiveness is in him, but it hasn’t been unlocked yet.”

Cameras caught both parents giving Tatum grief for missed free throws after Boston’s Game 3 comeback win in Indiana.

7. A Jaylen fan

The series doesn’t devote much attention to Tatum’s Celtics teammates, but Jaylen Brown is the subject of one brief storyline involving Edwards.

“I looked up to you when I was young, but you know what I’m saying? Pass the torch,” the Timberwolves star said to Brown before overtime during Boston’s early-season visit to Minnesota. “Can’t let y’all come in here and beat us.”

Edwards — who has a signed Brown jersey framed in his home — backed up that boast, leading the Wolves to a 114-109 win. He then lobbed a few shots at Tatum while celebrating in the locker room postgame.

“Y’all talking about ‘best player in the league,’” Edwards said. “Y’all tripping.”

The Celtics won the January rematch at TD Garden, with that game also needing overtime. The Celtics’ and Wolves’ two matchups this season (in Boston on Nov. 24 and in Minnesota on Jan. 2) will be appointment TV.
