OKC Thunder vs Dallas Mavericks Predicted Starting Lineups and Depth Charts for Oct. 27 | 2025-26 NBA Season

The OKC Thunder and Dallas Mavericks cross swords in what promises to be a thrilling regular-season matchup between two Western Conference contenders on Monday. The Thunder have picked up where they left off last season. Shai Gilgeous-Alexander and Co. are undefeated after three games and couldn't have hoped for a better start to their title defense.

Meanwhile, the Mavericks finally notched their first win in Cooper Flagg's era when they defeated the Toronto Raptors 139-129 at home on Sunday. Dallas will be on the second night of a back-to-back, and for them to build on their latest win, Jason Kidd's team need to play flawless basketball against a well-rested and in-form Thunder squad.

The rivalry between OKC and Dallas has been fierce. In terms of head-to-head record, there' not much to separate the two teams. In 178 regular-season games, the Thunder hold a slender 91-87 advantage. However, the Mavericks won the season series 3-1 last time around.
