The NBA journey of former first-round talent Keon Johnson has taken another turn, and this time, it leads him to the doorstep of the league’s reigning dynasty. According to a report by HoopsHype’s Michael Scotto, the former Brooklyn Nets starter has been claimed by the Maine Celtics, the Boston Celtics’ G League affiliate. This move presents a golden opportunity for Johnson to reclaim his NBA dream under the umbrella of the championship organization.
From Promising Prospect to a Journey of Instability

Selected 21st overall by the LA Clippers in the 2021 NBA Draft, Keon Johnson entered the league with high expectations thanks to his elite athleticism (6’5″ with a legendary vertical) and defensive potential. However, his path has been marked by change: traded to Portland mid-rookie year, then signing a two-way deal with the Brooklyn Nets.
The 2023-24 season was a pivotal step. Johnson impressed in the G League, earning a standard two-year contract from the Nets. And as Brooklyn pivoted into a rebuilding phase, his opportunity arrived.
A Season of “Mixed Returns” in Brooklyn: Opportunity Met With Inefficiency
On a tanking Nets squad, Johnson received the most significant run of his career: 79 games played, 56 starts, posting career-best counting stats of 10.6 points, 3.8 rebounds, and 2.2 assists in 24.4 minutes per game.
However, the flaws were also laid bare. With a vastly expanded role and career-high usage, his efficiency plummeted: shooting just 38.9% from the field and 31.4% from three-point range—numbers that fell short for a player seeking a permanent rotation spot.
“Victim” of a Draft Night Record and a Training Camp Surprise
In the summer of 2024, the Nets made history by selecting five players in the first round of the NBA draft. This influx of youth, combined with journeyman guard Tyrese Martin impressing during training camp, made Johnson expendable. Brooklyn made the tough decision to waive him before the season, opting for Martin’s immediate contributions instead.
The Path Forward in Maine: A Last Chance to Reach the Garden?
The Maine Celtics’ claim on Keon Johnson is a strategic low-risk, high-reward move. With Boston’s three two-way slots currently filled (Amari Williams, Max Shulga, Ron Harper Jr.), Johnson must now prove himself outright in the G League.
This is both a challenge and a perfect opportunity. Johnson will be refined within the Celtics’ renowned player development system—a pipeline that produced stars like Payton Pritchard. If he can improve his shooting efficiency, play with more consistency, and demonstrate maturity, a path back to an NBA roster, perhaps even with the Celtics themselves, remains wide open, especially for a team always seeking young talent to bolster its depth.
Keon Johnson joining the Maine Celtics is more than just a standard G League transaction. It’s the story of a former first-rounder at a critical career crossroads. He’s been an NBA starter, had his chance, and now must prove he belongs all over again. Under the shadow of the championship banners in Boston, Johnson’s redemption arc in Maine will be a compelling storyline to follow in the coming months.
