Mavericks build around Cooper Flagg, adding frontcourt depth to a promising core

The Dallas Mavericks spent the 2026 offseason building around one of the most exciting young foundations in the league, headlined by Cooper Flagg, and adding complementary frontcourt depth to complete the picture. For a franchise with a genuinely promising young core, the summer was about reinforcement and development rather than dramatic reinvention.

The Flagg era begins

Flagg represents the future of the franchise — a top overall draft pick with the kind of two-way potential that teams build around for a decade. Pairing him with a strong supporting cast, including big man Dereck Lively II, gives Dallas a young frontcourt with real upside and versatility. The offseason approach reflected a front office committed to nurturing that core, adding the right pieces to let its young talent develop rather than rushing to contend before the foundation is ready.

The signing of Santi Aldama, a versatile, floor-spacing forward, bolsters the frontcourt further and gives Dallas more flexibility in how it constructs its lineups. Aldama's length and skill complement the existing pieces well, and he's exactly the kind of useful, well-fitting addition that helps a young team round out its rotation.

A promising direction

What makes the Mavericks' offseason encouraging is the coherence of the plan: identify the young cornerstones, surround them with complementary talent, and build patiently toward contention. It's a refreshing clarity of direction, and it gives Dallas a foundation that could grow into something special over the next several years. The pieces are young, but the potential is significant.

Season outlook

The Mavericks enter next season as a young team on the rise in a loaded Western Conference. Realistically, this is still a developing group, and competing for a top playoff seed in the West is a tall order. But the trajectory is promising, and the continued growth of Flagg and the young core is what matters most. The goals are development, competitiveness and the establishment of an identity built around exciting young talent. Dallas's offseason wasn't about winning now — it was about building something that can win for a long time, and the foundation looks genuinely bright.
