The Boston Celtics have successfully rebuilt the end of their bench and maneuvered under the luxury tax line without touching their regular rotation players — and they even gave one young contributor a well-earned promotion in the process.
After trading away Xavier Tillman, Josh Minott, and Chris Boucher at the deadline without receiving players in return, the Celtics played a delicate “shell game” with those three roster spots. Many thought it would be nearly impossible to thread the needle when the season began, but Boston managed it through a series of calculated moves.
Following a string of 10-day contracts (including one for Charles Bassey), the Celtics upgraded two rookie contracts to fill two of the open spots. Max Shulga, drafted 57th overall and initially on a two-way deal, was promoted to a partially non-guaranteed standard contract. Amari Williams, selected 46th overall, received a similar partially non-guaranteed standard deal.
Charles Bassey’s second 10-day contract expired today, leaving the Celtics under the mandatory 14-man roster limit. To fill that final spot, Boston made the highly anticipated move of upgrading Ron Harper Jr.’s contract to a two-year, similarly structured partially non-guaranteed standard deal.
Harper Jr. Earns His Promotion
Harper has had a breakout season with the Celtics. While his averages sit at just 3.4 points per game, he has delivered several standout performances that have helped the team in critical moments.
He scored 22 points against the San Antonio Spurs, stepping up in a game where Jaylen Brown was ejected and giving Boston a real chance to win. He also had a strong showing against the Oklahoma City Thunder, finishing +15 in a two-point loss.
Head coach Joe Mazzulla recently praised Harper’s consistency and competitiveness.
“Ron has worked,” Mazzulla said. “The way he plays in games against San Antonio and OKC is the way he plays in a state-ready game, it’s the way he plays in G League games, it’s the way he plays in practice. So he cares about winning, he cares about competing. And he executes the details very well in all settings. His ability to think the game and compete is top notch. He’s getting better and better.”
The upgraded contract is significant because it makes Harper eligible for the playoffs — something two-way players are not allowed to do.
Celtics Slip Under the Tax Line
These moves have now positioned Boston approximately $38,000 under the luxury tax — a minuscule number that is the NBA equivalent of counting pennies at the cash register (and maybe using the “take a penny, leave a penny” tray). The Celtics still have one open roster spot, and that small cushion gives them enough flexibility to sign a player on the final day of the regular season and carry him into the playoffs in case of an emergency.
So it’s possible another minor move could still come before the postseason begins.
Final Word
The Celtics front office, led by Brad Stevens, has once again shown impressive roster management. They rebuilt the end of the bench without disrupting the regular rotation and managed to get under the tax line with room to spare. Upgrading Ron Harper Jr. is a fitting reward for a young player who has earned his opportunity through consistent effort and impactful performances.
With Jayson Tatum back and producing at a high level, the Celtics look even more dangerous heading into the playoffs. Their ability to stay flexible financially while maintaining a deep, competitive roster is a big reason why they remain one of the top teams in the Eastern Conference.
