The Boston Celtics are entering the 2026-27 NBA season under scrutiny following the trade of Jaylen Brown to the Philadelphia 76ers. While Jayson Tatum remains the primary offensive option, President of Basketball Operations Brad Stevens has restructured the roster to prioritize cap efficiency and balanced usage. During training camp, which includes a unique trip to The Citadel in South Carolina to study leadership, head coach Joe Mazzulla has emphasized the role of the player development staff, led by Craig Luscenat. Mazzulla noted that the organization has been working in the gym for months to establish a shared mental model for success. Regarding team cohesion, Mazzulla expressed a cautious outlook, stating that while preseason unity is common, true character is only revealed when facing adversity like losing streaks or media criticism. Jayson Tatum, entering his tenth season, reported having a ‘totally different perspective’ following a difficult previous year sidelined by a ruptured Achilles' tendon. After spending much of the last season watching practices from the weight room, Tatum stated he now possesses a ‘different type of joy’ for the game and playing with his teammates. In their preseason opener on October 8, the Celtics secured a 124-113 victory over the Cleveland Cavaliers. To prioritize developmental opportunities, the team sat its primary stars, including Tatum, Derrick White, and Paul George. ~~Assistant coaches Tony Dobbins and DJ MacLeay led the game in Mazzulla’s absence.~~ The bench demonstrated significant depth, led by Luka Garza, who recorded a double-double with 22 points and 10 ~~rebounds.
