In the first meeting between these two teams, OKC didn’t have a big man, and Dallas was playing without Luka Doncic. Luka will be in action for the Mavs, and the Thunder has Isaiah Hartenstein in the starting lineup, so it should be a slightly different matchup. I think Hartenstein’s addition moves the needle more in this matchup, particularly because of OKC’s backcourt defense. Luka Doncic and Kyrie Irving are one of the best scoring duos in the league, though, so slowing them down will be paramount to the Thunder not just winning but covering the spread. As for the Mavs on defense, I don’t think they have the ability to slow down OKC’s backcourt since they cannot simply clog the paint now that the Thunder has a talented big like Hartenstein.
