Harper Jr. Returns
Boston Celtics Sign Ron Harper Jr. to New 3-Year, $9 Million Contract for Roster Stability
Key Points
Boston used its 2026 NBA Draft to select Chris Cenac Jr. and Dillon Mitchell, adding two rookies to the roster as Harper's deal moves forward.
Dylan Harper, Ron's younger brother, was selected No. 2 overall in the 2025 NBA Draft by the San Antonio Spurs.
Ron Harper Jr.'s path to the Celtics included going undrafted in 2022, signing a two-way with the Raptors, then stints with the Las Vegas Summer League, Maine Celtics, and a two-way deal with the Pistons before earning a training camp invitation and converting to a standard contract.
Last season Harper played 29 games for Boston, averaging 4.2 points and 1.7 rebounds in about 11 minutes per game, with 3 starts and shooting 41.8% from the field and 35.0% from three.
Portland Trail Blazers are among teams showing serious interest in a Jaylen Brown trade, illustrating ongoing external pressure on Boston's offseason plans.
The Boston Celtics are set to bring back Ron Harper Jr. on a new three-year, $9 million deal, according to ESPN. The team is declining his existing $2.6 million team option for 2026-27 to make room for the longer agreement, which locks in the 26-year-old forward at $3 million per year.
Harper appeared in 29 games for Boston last season, averaging 4.2 points and 1.7 rebounds in about 11 minutes per game. He shot 41.8% from the field and 35% from three. The move gives the Celtics cost-controlled depth as they navigate a busy and uncertain offseason.
Harper's Long Road From Undrafted to Locked In
Harper went undrafted in 2022 out of Rutgers. He signed a two-way deal with the Toronto Raptors, then bounced through the NBA G League with the Maine Celtics and a two-way stint with the Detroit Pistons. Boston gave him an "Exhibit 10" training camp deal in September 2025. He earned a standard NBA contract by mid-season after injuries hit the bench.
Now, after years of uncertainty, Harper's representation said he wanted "stability and a clear role." He is getting both. The three-year deal is the longest contract of his career. Island Packet reported the Celtics view the agreement as a straightforward way to keep a player who already knows the system.
Why Declining a $2.6M Option Actually Saves Boston Money
Dropping the one-year option in favor of a three-year deal may look like spending more. But the math works under the NBA's current rules. The 2023 collective bargaining agreement (CBA) — the rulebook that governs player contracts — punishes high-spending teams. Boston is near the "Second Apron," a spending threshold that limits what moves a team can make.
At $3 million per year, Harper's new deal is considered a "win-trade" contract by analysts at The Ringer. That means his salary is small enough to keep Boston flexible, but large enough to use in a trade if a bigger deal comes along. Brad Stevens, the team's president of basketball operations, used a similar strategy with Sam Hauser in 2024.
Celtics Build Depth With Draft Picks and a Family Storyline
Boston also added two rookies in the 2026 NBA Draft: forwards Chris Cenac Jr. and Dillon Mitchell. With Harper now signed, the Celtics have 14 guaranteed contracts. That leaves just one open roster spot. The team finished 56-26 last season — the No. 2 seed in the East — before a first-round upset exit.
There is also a family angle. Ron's younger brother, Dylan Harper, was picked No. 2 overall in the 2025 draft by the San Antonio Spurs. The two brothers playing in the same league sets up what analysts are already calling a "Harper vs. Harper" storyline when Boston and San Antonio meet in 2026-27.
Jaylen Brown Trade Talk Looms Over Boston's Offseason
The Harper deal is the easy part of Boston's offseason. The harder question is Jaylen Brown. The Athletic reports that the Portland Trail Blazers are among teams showing "serious interest" in trading for the star guard-forward. Brown's future is the biggest unresolved issue the Celtics face heading into free agency.
Some local analysts on 98.5 The Sports Hub have pushed back on the Harper signing, calling it "rearranging deck chairs" after a painful first-round exit. But Stevens appears to be building a safety net. If Brown is traded, Boston now has Harper, Cenac Jr., and Mitchell as young wings to absorb that loss and avoid an immediate rebuild.
