Boston's preseason signals a pivot toward a youth-infused roster built around Jayson Tatum and Jaylen Brown. Joe Mazzulla faces a real test balancing an influx of unproven wings (Hugo Gonzalez, Josh Minott, Jordan Walsh, Baylor Scheierman) with a center rotation anchored by Neemias Queta, Luka Garza and Xavier Tillman. The aim is upside and cost-controlled development while preserving core star production. A Celtics Chronicle episode with Adam Taylor and Jason Timpf explores the potential shifts in offense, defense and rotation, with the full discussion linked for deeper context.
