Dallas traded Luka Doncic for Anthony Davis in February 2025 and hired Dusty May to rebuild around Cooper Flagg, who scored 21.0 points a game as a 19-year-old rookie last season. The franchise has run this play before, from the 1981 draft class that took three years to produce a winner to Dirk Nowitzki's 21-season run that ended in a championship.

One Year Versus Twenty-One
Nowitzki spent 21 seasons in a Mavericks uniform, the longest single-franchise tenure in NBA history, and that number is the yardstick every rebuild in Dallas gets measured against. Flagg is one year into his own run: 70 games at 21.0 points, 6.7 rebounds and 4.5 assists, shooting 29.5 percent from three as a 19-year-old. Dallas acquired Nowitzki in 1998, and the title didn't come until 2011. By that standard, Flagg's clock has barely started, and Dusty May now runs the program that has to get him there.
Defense as the Stated Bet
Nico Harrison called it plainly when explaining the Doncic trade: "I believe that defense wins championships." That's the operating philosophy under Dusty May now, tested against a defense that ranked 19th of 30 teams last season, an offense that ranked 27th, and a -5.2 mark that placed 22nd overall. The only banner in franchise history came in 2011, under a very different roster. Closing that gap is the whole bet on this rebuild.
Rebuilds Take Their Time
The 1981 draft brought Mark Aguirre and Rolando Blackman to Dallas, and the answer on whether that class worked didn't arrive until 1983-84, the franchise's first winning record and first playoff trip. Dallas traded Doncic to the Lakers for Davis in February 2025, and the rebuild around Flagg, Washington and Gafford has produced one full season on record so far: a 26-56 finish. The record now reads 0-0, with the real test starting October 21 at Houston. History in Dallas says the early number was never the real verdict.
