Dallas opened a new chapter after firing GM Nico Harrison, but the result looked familiar. The Mavericks committed 21 turnovers in a 123-114 loss to the Suns despite a strong showing from rookie Cooper Flagg.

The Dallas Mavericks and rookie Cooper Flagg dropped their first game after parting ways with general manager Nico Harrison, falling to the Phoenix Suns 123–114 at home on Wednesday.

Cooper Flagg explained what it was like to play against Suns star Devin Booker following the Mavericks' loss on Wednesday night.

Over the last three games with Russell in the starting lineup alongside Flagg, PJ Washington, Max Christie and Daniel Gafford, the Mavericks' offensive rating is 78.4. For comparison, the 2002-03 Nuggets hold the record for the lowest offensive rating in NBA history at 92.2.
