WALTHAM, Mass. -- A few weeks after the Boston Celtics were bounced from the first round of the Eastern Conference playoffs, Jonas Jerebko posted a black-and-white photo of an empty basketball court with the caption, "Time to get back to work," and the hashtag #myoffice.

Plenty of NBA players refer to the hardwood as their office, but Jerebko really means it. Earlier this year, the 29-year-old Swede purchased a 13,298-square-foot mansion from former Detroit Pistons teammate Ben Gordon for $2.2 million. The home, located in Oakland Township, Michigan, includes a regulation-sized NBA half court, a full workout area and locker room.

"I wake up in the morning, I go grab a smoothie out of the fridge, then I go down and get some shots up for a couple hours," Jerebko said. "It's a dream come true."

It has been a busy year for Jerebko beyond real estate ventures. In April, he and girlfriend Johanna Lunback, a Swedish model, welcomed their first child, a daughter, Izabel. In August, Jerebko ventured into the world of esports when he purchased the Renegades franchise and relocated the team to Detroit (the players live in another house Jerebko purchased, about 10 minutes from his new place).

In between, Jerebko had to patiently wait for the Celtics to navigate the early stages of free agency. With a nonguaranteed $5 million contract, Jerebko could have been waived if Boston had prevailed in the Kevin Durant sweepstakes. Some have joked that Jerebko and fellow nonguaranteed big man Amir Johnson were probably the only two people in the area rooting against Boston signing Durant, but Jerebko says he probably would have found a way back to the Celtics' roster regardless, even if it meant a dip in salary.

Even at his current pay grade, the Celtics have a bargain in Jerebko, who elevated to a starting role in last season's playoffs because of injuries and gave Boston a needed jolt before the team bowed in six games to the Atlanta Hawks. Since arriving in Boston at 2015's trade deadline -- a Danny Ainge coup in which the Celtics sent Tayshaun Prince, who might have otherwise been waived, to Detroit in exchange for Jerebko and Gigi Datome -- Jerebko has shot 40 percent from beyond the 3-point arc and brought an infectious, rim-crashing energy when he's on the floor.

With Boston's signing of Al Horford this summer, Jerebko shuffles back to a reserve role this season and will face competition for minutes with the addition of rookie Jaylen Brown, who can also play both forward positions. But Celtics coach Brad Stevens loves positional flexibility and Jerebko's versatility will ensure that he finds floor time.

Jerebko put together his best outing of the preseason on Thursday night as he registered 12 points, 5 rebounds, 3 assists, and a steal over 16 minutes in Boston's 100-97 win over the Brooklyn Nets at the Barclays Center. Jerebko made 4 of 5 shots, including three of the four 3-pointers he hoisted, while snapping out of a bit of a training camp shooting funk.

Neither Ainge nor Stevens were previously concerned about Jerebko's struggles.

"We know what Jonas can do well. And I think the most important thing is that, he hasn't shot it as well as he normally does, but sometimes that does happen to shooters in the first couple weeks because your legs are gone," Stevens said. "So, at the end of the day, we need Jonas to space the floor for us and be a versatile defender."

After a summer in which many hours were logged in that home office, Jerebko says he believes his shooting numbers will ultimately rise this season.

"I've been trying to speed up my release so I can get my shot off quicker," he said. "I feel like when I first got into the NBA, my shot was not really something that people knew that I did. But every year I've become better and better and, the last two years, I've been shooting 40 percent from 3. I'm looking to go even [higher]. I want to be a 45 percent 3-point shooter. I know I can do it. It's just a matter of the shots that I pick -- then just doing it every day."

Jerebko is bullish on Boston's chances to live up to the preseason hype, with many pegging the Celtics to be Cleveland's top challenger in the East. Said Jerebko: "We can beat any team in this league, we just gotta be consistent enough during the whole season and then be healthy in the playoffs."

Jerebko marvels that he has been playing professional basketball -- first in Sweden, then in Italy before the Pistons drafted him with the 39th pick in the 2009 NBA draft -- for over a decade now. At 29, he's one of the "older" players on Boston's roster, but he roots hard for the younger guys who are competing for the same minutes. Like during an exhibition game last week in Connecticut against the Hornets, Jerebko was bouncing around on the bench when rookie Ben Bentil scored his first NBA basket.

"He's a great guy, great story behind him," Jerebko said. "I was just like, 'C'mon, man, score your first bucket!' So when he scored that first bucket, I was just as happy as him."

Jerebko seems genuinely content with everything on the court and off. Having a young daughter provides good work-life balance. His Instagram is speckled with snapshots of Izabel, now 7 months old, and her doting dad. Jerebko is hoping that, as she grows, the family can bring back home their two dogs -- Hank and Roy -- who are staying with family to limit the craziness at home with a little one.

"It's a nice balance," Jerebko said. "When you're a rookie you didn't have that kind of balance. You kinda live in the gym and then you come home and you play video games or your day is not as productive as it is now."

Of course, having that home office makes Jerebko particularly productive in the offseason.
