Boston heads into 2025-26 with Jayson Tatum out after a torn Achilles, pivoting from title contention to development around Brown and White. Holiday and Porzingis moved on, leaving veterans to depart as the roster leans into youth. Jordan Walsh, Baylor Scheierman, Josh Minott, Luka Garza, Hugo Gonzalez, Amari Williams and Max Shulga are primed to seize early rotations, with Payton Pritchard and Sam Hauser likely anchoring surrounding lineups as Boston stacks for long-term upside.
