Maine Celtics Overview
The Maine Celtics are a professional basketball team competing in the NBA G League as an affiliate of the Boston Celtics. Based in Portland, Maine, the team plays its home games at the Portland Exposition Building. Founded in 2009, the franchise has built a competitive identity in the developmental league while serving as a vital pipeline for Boston Celtics talent. The organization is owned by the Boston Celtics and maintains a direct developmental relationship with the NBA franchise. The team’s colors are green, black, white, and brown, with Vistaprint serving as the main sponsor. Under the current leadership of President Dajuan Eubanks, General Manager Jarell Christian, and Head Coach Phil Pressey, the Maine Celtics continue their mission of developing players for the NBA while competing for championships in the Eastern Conference.
Founding and Organizational Origins
On February 25, 2009, the NBA Development League awarded the city of Portland, Maine, with an expansion franchise, marking the beginning of professional basketball’s presence in the state. The team announced its name, “Red Claws,” on April 2, 2009, following a naming contest that drew thousands of entries. The winning name paid homage to Maine’s thriving lobster fishing industry while also honoring legendary Boston Celtics coach Red Auerbach through the use of “Red” in the title. The name selection process considered several other options including Beacons, Crushers, Destroyers, Swarm, and Traps before settling on Red Claws.
On July 21, 2009, the Red Claws announced Austin Ainge as the franchise’s first head coach, establishing the initial leadership structure for the new organization. The team prepared for its inaugural 2009–10 season at the Portland Exposition Building, which would serve as the home arena for all home games. From the very beginning, the franchise demonstrated strong community support and market appeal, laying the foundation for sustainable operations in the Maine market.
Growth Into NBA G League Competition
During the 2009–10 season, the Maine Red Claws achieved remarkable attendance success by becoming the only D-League team to sell out all 24 of their home games. This impressive streak continued through the following seasons, ultimately reaching 48 consecutive sold-out games before concluding during the 2011–12 season. The strong fanbase demonstrated Maine’s appetite for professional basketball and validated the franchise’s decision to locate in Portland.
For the team’s first two seasons, the Red Claws maintained a split affiliation between the Boston Celtics and the Charlotte Bobcats. The affiliation structure evolved during the third season to include partnerships with Boston, Charlotte, and the Philadelphia 76ers. On June 21, 2012, the Red Claws announced a hybrid affiliation agreement with the Boston Celtics, making the Celtics the franchise’s sole affiliate. This exclusive relationship strengthened the developmental pipeline and aligned the Red Claws more closely with one of the NBA’s flagship franchises.
Maine Celtics Competitive Journey
The Maine Celtics have evolved from an expansion franchise into a consistently competitive force within the NBA G League. Throughout their history, the organization has experienced multiple playoff appearances, division championships, and most recently, a conference championship in 2024. The journey from the original Maine Red Claws to the current Maine Celtics reflects both on-court success and organizational growth under different ownership structures.
Early Seasons and Development (2009–2014)
The Maine Red Claws made their first playoff appearance in April 2013, entering the postseason as the eighth-seeded team. The team faced the Rio Grande Valley Vipers in a best-of-three-game opening round series but was swept in two games. Despite the playoff exit, this appearance represented a significant milestone for the young franchise, demonstrating that the organization could compete at a high level within the developmental league.
On July 16, 2014, the Red Claws announced that head coach Mike Taylor would not return for a third season after compiling a 45–55 record over two seasons with the team. The organization moved swiftly to find his replacement, eventually hiring Scott Morrison on August 2, 2014. Morrison brought extensive coaching experience, having spent 11 seasons as head coach of Lakehead University’s Lakehead Thunderwolves in Ontario, Canada, while also serving as a D-League assistant during the 2013–14 season. His hiring represented a commitment to player development and long-term organizational stability.
Breakthrough in Eastern Conference (2015–2017)
Under Scott Morrison’s leadership, the Maine Red Claws experienced their first sustained period of competitive success. The team won three consecutive Atlantic Division championships in 2015, 2016, and 2017, establishing themselves as the class of their division within the G League. These championship seasons demonstrated the franchise’s ability to develop talent while achieving tangible on-court results that resonated with fans and stakeholders alike.
The success caught the attention of the NBA’s top levels when, on June 21, 2017, Brad Stevens, then head coach of the Boston Celtics, named Scott Morrison as an assistant coach with the Celtics. This promotion represented the highest-profile staff departure in franchise history and validated the Red Claws’ developmental philosophy. The move also highlighted the growing connection between the G League franchise and its NBA parent team. In 2017, the D-League officially rebranded as the NBA G League through a sponsorship agreement with Gatorade, marking a new era for developmental basketball.
Boston Celtics Ownership and Modern Era (2019–Present)
On July 25, 2019, the Boston Celtics announced their intention to purchase the Maine Red Claws franchise from original owners Bill Ryan and Bill Ryan Jr., who had chaired the ownership group through the team’s first decade of operation. Before the sale, the Red Claws had been one of the few remaining independently owned G League franchises. The sale, finalized on October 15, 2019, continued the industry trend of NBA teams acquiring their developmental affiliates to maintain closer control over player development pipelines.
During the abbreviated 2019–20 season, Bryce Brown set a franchise record by making 11 of 11 three-point attempts in a 128–123 loss to the Delaware Blue Coats on December 7, 2019. The season was subsequently curtailed in March 2020 due to the COVID-19 pandemic while the Red Claws held first place in their division. The following 2020–21 season was delayed and eventually relocated to a single-site bubble format in Orlando, Florida, but the Celtics organization opted to have the Red Claws withdraw from participation.
On May 24, 2021, the Boston Celtics officially announced the rebranding of the franchise from the Maine Red Claws to the Maine Celtics, effective for the 2021–22 season. This rename strengthened the visual and operational connection to the NBA franchise while maintaining the team’s Maine-based identity. The rebranding introduced new team colors, logos, and marketing while preserving the community ties that had been built over the previous twelve years.
Current Leadership and Direction (2025–Present)
On July 2, 2025, the Maine Celtics announced Phil Pressey as the 11th head coach in franchise history, replacing Tyler Lashbrook who remained with the Boston Celtics as an assistant coach. Pressey’s appointment represented a commitment to hiring individuals with direct NBA experience and connections to the parent franchise. The coaching transition occurred during an exciting period for the organization following its 2024 Eastern Conference championship.
Under the current leadership structure, President Dajuan Eubanks oversees organizational operations while General Manager Jarell Christian manages roster construction and player personnel decisions. The trio of executives works in coordination with Boston Celtics leadership to ensure alignment between developmental goals and franchise needs. This integrated management approach reflects the modern G League model where developmental teams operate as extensions of their NBA parent organizations.
Philosophy and Competitive Strengths
The Maine Celtics maintain a development-first philosophy while competing aggressively for championships within the NBA G League structure. The organization prioritizes player growth and NBA readiness, using game experience at the G League level to prepare athletes for the demands of the NBA. The franchise leverages its Boston Celtics affiliation to provide players with exposure to professional systems, advanced training methodologies, and potential call-up opportunities.
Key Milestones and Major Moments
The franchise’s history includes several landmark achievements that define its competitive legacy. The three consecutive division championships from 2015 to 2017 established the organization as a consistent winner. The 2024 Eastern Conference championship represented the pinnacle of on-court achievement, marking the first conference title in franchise history. The sale to the Boston Celtics in 2019 and subsequent rebranding in 2021 represented transformational organizational moments that reshaped the franchise’s identity and future direction.
Maine Celtics Achievements and Results
The Maine Celtics have built a decorated history of accomplishments since their founding in 2009. While the franchise has yet to capture a G League championship, the team has established itself as a perennial contender within the Eastern Conference through division titles, playoff appearances, and conference championships. The organization’s trophy case reflects both team success and individual player development achievements.
Eastern Conference Championships
The Maine Celtics claimed their first Eastern Conference championship in 2024, representing the franchise’s most significant achievement since its founding. This conference title validated years of competitive building and organizational investment under Boston Celtics ownership. The championship run showcased the team’s ability to perform at the highest level within the G League postseason structure.
Atlantic Division Championships
The Maine Red Claws dominated the Atlantic Division from 2015 through 2017, capturing three consecutive division titles during this period. These championships came during the Scott Morrison coaching era and represented the franchise’s first sustained run of postseason success. The three consecutive titles remain a franchise record for consecutive championship wins in any category.
Notable Records and Performances
Bryce Brown’s perfect 11-for-11 performance from three-point range on December 7, 2019, set a franchise record for single-game three-point shooting percentage with a minimum of 10 attempts. This performance occurred during a competitive game against the Delaware Blue Coats and demonstrated the offensive firepower the franchise could produce. The 48-game home sellout streak from 2009 to 2012 established attendance records within the early D-League and demonstrated Maine’s strong basketball fanbase.
