Spurs vs. Thunder Prediction
The NBA Western Conference Finals sees the No. 1 seeded Thunder host the No. 2 seeded Spurs in a star-studded affair. While the Thunder are favored to win on Kalshi, its important to remember the Spurs won the regular season series 4-1.
Action Network writer Matt Moore has a Spurs vs. Thunder prediction of Oklahoma City wins by over 6.5 points NO (1.93x) this evening. Here are some quotes from Moore on why he likes the Spurs to cover as road underdogs in Game 1:
"I like this matchup a lot for San Antonio because of the specific mechanisms they can get to. By the end of this series, OKC is going to be forced to switch everything. But in Game 1, I wouldn't be surprised if the Thunder try to play traditional drop coverage, thinking, "We just need to execute our base plan." But when they drop, the Spurs' guards are going to get downhill and shred them."
