Dallas finished last season 26-56 with the league's 27th-ranked offense while its defense held up respectably in the middle of the league. Cooper Flagg's rookie season and Nico Harrison's defensive philosophy are the whole bet now, because Dallas's own first-rounders are mostly gone or swap-only before 2030 arrives.

Flagg Carries The Argument
Cooper Flagg played 70 games at 19 and averaged 21.0 points, 6.7 boards and 4.5 assists, numbers built for a franchise centerpiece, not a rookie feeling his way through the league. Dusty May inherits that talent along with a defense that finished 19th, respectable for a roster reshaped by last year's trade of Luka Dončić around Flagg, P.J. Washington and Daniel Gafford. Willie Green's arrival on the bench, reported by Hoops Rumors, adds a voice built around structure, which fits Nico Harrison's stated bet that defense wins championships.
The Offense Still Can't Score
The other half of the ledger is uglier: Dallas's offense finished 27th-ranked in the league, beating out only three teams for efficiency, a number Flagg's box score alone can't fix. Max Christie shot 40.4 percent from three and John Poulakidas hit 40.3 percent in a small sample, but Washington, Gafford and Naji Marshall all shot below 33 percent from deep, thinning the spacing around Flagg's drives. Santi Aldama, the roster's best offensive big at 14.0 points and 35.0 percent from three, opens camp day-to-day with a right knee issue, alongside Kyrie Irving, who returns at $39.5 million against a left knee of his own.
The Cap Sheet Settles It
Payroll sits at $197.9 million, above the $165.0 million cap and $2.5 million shy of the $200.4 million tax threshold, room Dallas can still use in-season. What the Mavericks don't have is draft leverage: their own first-rounders through 2030 are protected or swap-only, and second-round picks head to the Clippers in 2028 and the Nets in 2029 and 2030. That means the answer to whether this rebuild works has to come from the players already on the roster, starting with how fast Flagg's growth outpaces the offense he's still carrying alone.
Will the Mavericks make the playoffs in 2026-27?
Nothing is settled before the October 21 opener at Houston, but last season's 26-56 finish and 27th-ranked offense mean a return trip depends on real offensive improvement, not just Cooper Flagg's growth.
What is the Mavericks' identity under Dusty May?
Nico Harrison's stated bet that defense wins championships still drives the roster build, and a defense that finished 19th last season gives Dusty May a real foundation to work from.
