Celtics Sign Former Lottery Pick Devin Carter to Exhibit 10 Contract Amid Roster Reshuffle

The Boston Celtics have made another strategic roster addition by signing former Sacramento Kings lottery pick Devin Carter to an Exhibit 10 contract according to multiple reports. The 6'3" guard, selected 13th overall in the 2025 NBA Draft, gets a fresh opportunity after being waived by the Kings following their recent trade with the Atlanta Hawks. This move continues Boston's trend of identifying undervalued talent as they finalize their roster for the 2026-27 season.

Carter's College Pedigree and NBA Potential

During his standout season at Providence College, Carter averaged 15.7 points, 8.7 rebounds and 2.8 assists while earning Big East Defensive Player of the Year honors. His two-way play at Providence drew comparisons to current Celtics guard Derrick White, with both players showing similar defensive intensity and offensive versatility. The Celtics organization reportedly sees untapped potential in Carter, who struggled to find consistent minutes during his rookie season with Sacramento. Carter's college coach Ed Cooley praised his work ethic and defensive instincts, qualities that align with Boston's team identity.

An Exhibit 10 contract provides Carter the chance to compete for a roster spot during training camp while giving Boston front office flexibility. The deal allows the Celtics to convert it to a two-way contract if Carter impresses during preseason activities. This type of low-risk signing has become a hallmark of Brad Stevens' roster-building strategy, having previously used similar contracts to develop players like Sam Hauser and Luke Kornet into rotation pieces.

Training Camp Competition Heats Up

Carter's arrival adds depth to what promises to be one of the most competitive Celtics training camps in recent years. His defensive skills could create interesting lineup possibilities alongside guards Derrick White and Payton Pritchard. Several analysts suggest Carter's presence might allow Pritchard to focus more on his offensive strengths as a sparkplug scorer off the bench. CelticsBlog noted that Carter's skill set makes him an ideal candidate for Joe Mazzulla's system, which values positional versatility and defensive intensity.

The frontcourt competition appears equally intense. Center Neemias Queta, who re-signed with Boston this offseason, acknowledged the challenge posed by newly acquired big man Mitchell Robinson. "You can't really count us out," Queta told CLNS Media regarding the team's revamped frontcourt rotation. When asked about potential roles, Queta deferred to head coach Joe Mazzulla, stating "That's a [Mazzulla] thing to figure out." This internal competition reflects Boston's depth at center, where they now have Robinson, Queta, and Luka Garza vying for minutes behind likely starter Al Horford.

Defensive Identity Remains Priority

Boston's offseason moves suggest a continued emphasis on defensive versatility. The addition of Robinson from New York and now Carter gives the Celtics multiple options to maintain their defensive intensity. Robinson, known for his elite rim protection and rebounding, predicted "this is going to be a great year for me" during recent media appearances. His presence should help Boston improve their rebounding numbers after ranking middle of the pack last season.

Hugo Gonzalez, another young Celtics player involved in trade rumors this summer, emphasized the team's collective mindset. "I'm working for winning with the Boston Celtics," Gonzalez told EuroHoops, reflecting the organization's championship expectations. Gonzalez's comments come amid speculation about his role following Boston's roster changes. The Spanish forward remains a developmental project but could carve out a niche with his shooting and defensive length.

Roster Construction Philosophy

The Carter signing represents Boston's latest effort to identify undervalued talent. Exhibit 10 contracts allow teams to evaluate fringe NBA players without significant financial commitment, a strategy the Celtics have employed effectively in recent seasons. This approach has helped Boston maintain roster flexibility while developing young players who can contribute in specific roles. MassLive noted that Carter was once viewed as a potential lottery steal before falling out of Sacramento's rotation.

Boston's front office appears focused on surrounding stars Jayson Tatum and Jaylen Brown with defensive-minded role players. The additions of Robinson and Carter complement existing defensive stalwarts like White and newly acquired forward Paul George. These moves suggest the Celtics aim to preserve the defensive identity that has been central to their success under Mazzulla, who emphasizes switchability and perimeter pressure. The Sporting News described Carter as a "defensive menace" who could thrive in Boston's system.

Tatum's Continued Development

While roster moves generate headlines, Celtics fans received encouraging signs about franchise cornerstone Jayson Tatum's offseason progress. The All-NBA forward participated in a high-profile pickup game at Duke University alongside stars like Paolo Banchero and Kyrie Irving. The scrimmage showcased Tatum's refined offensive game and explosive athleticism, with First to the Floor noting he looked "explosive" during the session. These offseason workouts suggest Tatum is expanding his already formidable offensive repertoire.

Tatum's continued evolution remains vital for Boston's championship aspirations. The 26-year-old is coming off another stellar season where he averaged 26.9 points, 8.1 rebounds and 4.9 assists while leading the Celtics to the Eastern Conference Finals. His offseason work suggests another potential leap in his game, particularly in playmaking and late-game execution. ESPN analyst Mike Schmitz recently noted Tatum's improved decision-making in pick-and-roll situations during summer workouts.

Eastern Conference Landscape

Boston's roster moves occur against the backdrop of a competitive Eastern Conference. Several rivals have made significant additions, making the Celtics' depth acquisitions potentially crucial. The Carter signing and other roster tweaks position Boston to maintain their status as conference contenders. Liberty Ballers recently ranked the Celtics among Philadelphia's biggest threats in the East, citing their defensive versatility and star power.

The Celtics' ability to integrate new pieces like Carter and Robinson while maintaining defensive cohesion could determine their success. With training camp approaching, these under-the-radar moves may prove just as important as the team's more headline-grabbing offseason transactions. NBC Sports Boston noted that Boston's defensive rating could improve significantly with their new additions, potentially making them the conference's most complete team.

What's Next for Boston

As the Celtics prepare for training camp, the coaching staff faces interesting decisions about rotations and roles. Carter's performance in preseason will determine whether he earns a roster spot or two-way contract. His development could provide valuable backcourt depth behind established guards. The Providence Journal reported that Carter has been working extensively on his three-point shooting this summer, which could help him carve out a role in Boston's offense.

The organization's ability to identify and develop talent like Carter has been a hallmark of their sustained success. This latest signing demonstrates Boston's commitment to leaving no stone unturned in their pursuit of championship-level depth. With the 2026-27 season approaching, the Celtics appear poised to build on their recent success while integrating new pieces into their system. How Bout Them Celtics speculated that Boston might not be done making moves, with additional roster tweaks possible before opening night.

Historical Context

The Carter signing continues a long tradition of the Celtics finding value in former lottery picks. Players like Evan Turner, Jeff Green and Jae Crowder all revived their careers in Boston after being acquired via trade or free agency. The Celtics' developmental staff has earned a reputation for helping players maximize their potential in defined roles. As Sactown Sports noted, Carter's skill set might be better suited for Boston's system than Sacramento's, giving him a legitimate chance to stick in the NBA.

This signing also represents another connection between the Celtics and Providence College. Boston has a history of giving opportunities to Friars alumni, including current assistant coach Kevin Stacom and former player Ryan Gomes. Carter's local ties could make him a fan favorite if he earns rotation minutes, adding another layer of intrigue to his training camp battle.
