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.
