On Monday, the Boston Celtics completed their triumphant march to Banner 18, defeating the Dallas Mavericks in the NBA Finals in five games.

Boston officially breaks ties with the Los Angeles Lakers for the most NBA championships in league history. The Celtics were the most dominant team in basketball from wire to wire this season, capping off their impressive campaign with a title. But now the question comes: Can they do it again?

Of course, it’s only fitting that we discuss what the Celtics need to do to repeat this just a day after winning the Finals. So without further ado, here are the three most important moves Boston needs to make to get back to this position next year.

Yes, the Celtics undeniably have perhaps the most important wing duo in the NBA between Jayson Tatum and Jaylen Brown. However, the team lacks depth beyond that.

Sam Hauser was the only other swingman in Boston’s postseason rotation, though he has a club option for 2024-2025. Since his salary for the coming year would be around $2 million, Boston will retain him. Still, there’s no harm in upgrading the position and relegating the sniper to a reserve role.

Boston will be on the second apron this season, especially once they officially sign Tatum to a five-year, $315 million contract extension. The financial constraints will make it difficult for the Celtics to improve the roster with outside additions in free agency. But they have control over their next four first-round selections and additional draft capital, so they may have a few tricks up their sleeve.

Hauser performed admirably in his limited role in the playoffs, evidenced by the fact that he earned the highest net rating (14.2). He averaged 5.4 points and 2.2 rebounds in 14.9 minutes per game, shooting 38 percent from 3. Despite being a 3-point shooter, he has limitations in his game.

It seems necessary to add another forward who can spell Tatum and Brown for longer than short bursts and give the Celtics additional playmaking ability.

Kristaps Porzingis got his championship ring, but at what cost? In the aftermath of the Celtics’ win over Dallas, reports surfaced that the big man will require surgery and “a few months” of recovery.

Shortly after returning for the finals after an extended absence due to a right soleus strain, Porzingis suffered a unique and different injury. He dislocated his left tibialis posterior, sidelining/limiting him for the rest of the series. Despite his immense talent, the Latvian has struggled to stay healthy throughout his career, so adding an insurance option could be beneficial.

The Celtics tried to do that before this year’s trade deadline by acquiring Xavier Tillman from the Memphis Grizzlies. But that didn’t go as expected. What now?

Moreover, 38-year-old Al Horford is not getting any younger. Despite still playing basketball at a high level, the veteran center ended an all-time record of futility in the playoffs by winning a title. Can we see him ride off into the sunset after finally getting the monkey off his back?

Porzingis proved to be one of the two key missing links the Celtics needed to get over the hump, along with Jrue Holiday. Still, concerns about the former’s availability should push Boston to get ahead of the game as best it can. We all witnessed what happened this postseason. Taking measures if a similar situation arises is a luxury that this group can and should consider.

Only Hauser and fellow Celtics teammate Payton Pritchard had higher net ratings than Derrick White this season. Nevertheless, the two before him did so in limited roles, with the latter contributing significantly to Boston’s success.

Since landing with the Celtics in 2022, White has only continually improved in all facets of his game, especially offensively. He averaged career highs almost across the board (points, rebounds, assists, steals, blocks and 3-point percentage). His two-way skills as a playmaker, shot maker and defensive stalwart have swung the pendulum in the Eastern Conference.

White has essentially been a souped-up version of what Marcus Smart was during his tenure with the Celtics. As the crucial glue man who makes Tatum and Brown’s lives easier, his presence makes all the difference.

The Celtics are eligible for a four-year, $126 million extension and hope to finalize a deal with White this summer. He is entering the final year of his current pact, although he has become an indispensable asset for Boston. So it’s hard to imagine the two parties not finding common ground to renew their marriage.
