The Oklahoma City Thunder and San Antonio Spurs face off in Game 1 of the Western Conference finals on Monday, one of the most anticipated playoff series in recent years.

Oklahoma City and San Antonio both won more than 60 games and eclipsed a .750 win percentage in the regular season. This is only the third time since the conferences were formed in 1970 that two teams with a regular-season win percentage of .750 or better have met in the conference finals. The last time this occurred was in 1981, when the Boston Celtics faced the Philadelphia 76ers.

The Spurs went 4-1 against the Thunder in the regular season, including three wins in a two-week span in December. This sets up a showdown between budding rivals that could dominate the league for years to come. The two teams' average age weighted for playing time this postseason is 25.5, the youngest combined age in the conference finals since 1970.

In their quest to earn consecutive NBA titles, Oklahoma City has eight straight victories to start the playoffs—the fourth-longest win streak to begin a postseason by a defending champion. San Antonio swept the Portland Trail Blazers in the first round before defeating the Minnesota Timberwolves in six games.

Thunder star Shai Gilgeous-Alexander, who won his second MVP award on Sunday, is averaging 29.1 points and 7.1 assists on 51.4% shooting from the field this postseason. Spurs star Victor Wembanyama, who finished third in the MVP voting, leads the team with 20.3 points, 10.7 rebounds, and 4.1 blocks per game.
