Lock in your Spurs vs. Thunder prediction on PrizePicks before tip-off of Game 1.
- During the regular season, the Spurs went 4-1 outright and 3-2 against the spread (ATS) vs. the Thunder.
- However, Oklahoma City was without most of its starters for February 4’s matchup. In December, San Antonio went 3-0 outright and ATS against a healthy Thunder squad.
- In the regular season, the Thunder allowed a 44.0% 3-point shot distribution (25th), per Dunks & Threes.
- Opponents have shot 36.0% from beyond the arc vs. OKC in the playoffs, which is the second-worst mark among active teams.
- Excluding February 4’s matchup when the Spurs faced a thin Thunder lineup, San Antonio posted a healthy 36.0 3-point shots and 13.3 made triples per game while shooting 36.8% from deep in head-to-head matchups during the regular season.
- In the playoffs, the Spurs have shot a blistering 38.4% from beyond the arc (tied for third).
- The Thunder also tout an impressive 38.4% mark on 3-pointers, but San Antonio has limited opponents to 31.9% on treys during the postseason (second-lowest).
- Led by Wembanyama, the Spurs can hang with Oklahoma City around the rim. If San Antonio wins the 3-point battle, its head-to-head success may keep up.
