San Antonio earned the top seed last season, finishing three games ahead of the Thunder and gaining home-court advantage through the Western Conference Finals.
Oklahoma City, however, defeated the Spurs in six games despite San Antonio winning the first two at home.
This year's battle for the top spot is a long way from being over. The Thunder still has 37 games remaining to earn home-court advantage, and OKC and San Antonio have two games remaining against each other.
