Thunder vs Spurs Western Conference Finals Series Preview, Picks
Brandon Anderson: Thunder on paper, Spurs in practice. What do we do? I’m not really sure where I’m at on this series conceptually, but I am incredibly excited to dig into these numbers.
Matt Moore: I have no idea what's going to happen, pick 'em. Just to be clear right at the top, you might think, "Cool, you're telling us neither of you knows anything." No, we’ve got bets. Don't worry, I actually have a side I'm backing. I'm just saying that as a fan, I’m genuinely fascinated. I look at one angle and think one thing, then I look at the counter and flip.
My best bet is on the series spread. I'm laying the games and taking Oklahoma City -1.5 games on the series spread at -110. My model projects this out at -123, so I'm catching about 13 cents of value. I learned my lesson in the previous round about getting too cute with exact game outcomes, so I'll just trust the model's value on the game spread.
Brandon Anderson: My best bet is going to be a light play on the Oklahoma City Thunder to win the series from behind at +325 at Bet365. Part of this is because I want to see this young Thunder team get punched in the mouth and face some real playoff adversity, and see how they respond.
But my actual primary best bet for the series is a full-scale Stephon Castle points and threes series escalator. I’ve got four different bets locked in on him, ranging from standard juice all the way up to a massive long shot. I’m also holding out some Western Conference Finals MVP long shots on Castle at 70-1 and De'Aaron Fox at 100-1, both at DraftKings.
When the Thunder Have the Ball
Matt Moore: When you look at Oklahoma City’s offense versus the San Antonio defense, the regular-season tape shows a glaring trend. The Thunder run an elite pick-and-roll offense, particularly with Shai Gilgeous-Alexander, but that efficiency completely plummeted against the Spurs' coverage.
Shai normally operates at a blistering 1.20 points per possession in pick-and-roll actions. Against San Antonio, that dropped to 0.90 points per possession—a massive 30-point drop in offensive rating. Victor Wembanyama completely evaporates the lower third of the floor with his length.
It doesn't just mean Shai can't challenge at the rim; it means perimeter defenders can guard Shai entirely differently because they know Victor obliterates any driving angles behind them. Stephon Castle also had immense individual success bothering Shai on the perimeter during their regular-season meetings.
Brandon Anderson: On the other side of the ball, the metrics look like a dead-even matchup, perhaps with a slight structural advantage to San Antonio. Both of these teams are top-five in two-point field goal percentage and top-ten in three-point percentage.
The statistical battleground comes down to the four factors. The Thunder do not care about offensive rebounding, which completely wastes a strength against a Spurs defense that ranks number one in defensive rebounding anyway.
In addition, OKC thrives on taking care of the ball, but the Spurs' defense doesn't look to force turnovers as part of their scheme, which neutralizes another Thunder edge.
The ultimate question here is whether Shai can get to the free-throw line. The Spurs commit the fewest fouls of any team in the NBA. In their regular-season matchups, Shai’s free-throw attempts went four, five, eight, and then 13, showing he started to figure it out late, but overall, OKC was held to a 20% free-throw rate, which is below their average.
We have to ask: is SGA in a tier below Wembanyama right now? Shai won a Finals MVP last year, but over his last two playoff runs, his metric footprint dropped by about 3 OBPM. He was awesome against the Suns, but against the Lakers, he was sub-one in BPM and went negative in Games 1 and 2. If the Spurs don't foul him, their defense has a tangible edge.
Matt Moore: We also have to track Jalen Williams' health. J-Dub is fully healthy and will slot right back into the starting lineup without a minute restriction. He had a tough regular season against San Antonio, but if he plays like he did in his limited playoff minutes, it could be curtains early for the Spurs.
If he struggles, it doesn't hurt OKC because they built elite redundancy with AJ Mitchell. Alex Caruso is also going to have a massive offensive series, shifting into gaps, slipping screens and hitting timely corner threes.
When the Spurs Have the Ball
Matt Moore: This is where things get incredibly nerdy. San Antonio runs a ton of Spain pick-and-roll actions using two screeners simultaneously. It forces three defensive players to navigate a highly complex sequence. This completely scrambles Oklahoma City’s defensive principles because the Thunder want to crowd you in tightly packed spaces.
By bringing two screeners up, the Spurs open up the entire backside of the floor for their ball-handlers to get downhill. San Antonio's offense actually scored 0.96 points per possession in the pick-and-roll against OKC's top-rated coverage.
De'Aaron Fox, Dylan Harper, and Stephon Castle consistently got downhill and killed Isaiah Hartenstein and Chet Holmgren with floaters. It forced the Thunder to switch, which they absolutely hate doing because it pulls them out of their standard shell coverage. If they switch, it leaves a guy like J-Dub trying to box out a 7-foot-4 pterodactyl under the rim on lob entries.
I don't trust the Thunder shooters early, but Julian Champagnie, Keldon Johnson, and Devin Vassell have all had great playoff shooting stretches. The Spurs simply have more individual offensive weapons to account for.
Brandon Anderson: I disagree here, because this is exactly where I think Oklahoma City wins the series. If I rank the four units on the floor, it goes Thunder Defense in a tier of its own, followed closely by Spurs Defense and Thunder Offense, with the Spurs Offense sitting as the clear weak link.
The Spurs are elite inside, but the Thunder's defense eliminates two-pointers, holding opponents under 49% at the rim. OKC allows a high volume of three-point attempts, which dares average shooting guards like Castle and Fox to beat them from deep.
The two major variables are turnovers and offensive rebounding. The Thunder are number one in the league in points off turnovers, but the Spurs are top-five in fewest turnovers allowed.
In the regular season, San Antonio maintained a stable 12% turnover rate against them, which limits OKC's transition offense. However, Stephon Castle was highly turnover-prone against the Thunder, averaging 4.3 giveaways per game.
If OKC speeds up these young guards, it turns into fast-break points. The Spurs do have a rebounding edge, as Luke Kornet averaged four offensive rebounds per game against the Thunder. But offensively, this puts an enormous burden on Wembanyama to single-handedly beat a historic, juggernaut defense.
History shows us that complete teams beat one-man shows in the postseason.
The Player Hierarchy
Tier 1: Victor Wembanyama, Shai Gilgeous-Alexander
Tier 2: Jalen Williams, Chet Holmgren
Tier 3: De'Aaron Fox, Stephon Castle, Dylan Harper, AJ Mitchell, Cason Wallace, Alex Caruso
Brandon Anderson: I have Wembanyama and Shai at the top, followed by the secondary Thunder stars. I do not trust De'Aaron Fox as a legitimate number two option on a championship team; he had a terrible second-round series against Minnesota, registering a miserable minus-four BPM on 47% true shooting until a noisy Game 6 blowout.
The Thunder are going to be perfectly content letting Fox take a high volume of shots and living with the results. Two weeks from now, the entire basketball world is going to be putting one of two names into a trade machine: J-Dub if the Thunder lose, or De'Aaron Fox if the Spurs lose.
Matt Moore: The film showed me the exact opposite context. Fox looked incredibly comfortable dealing with Oklahoma City's physical style of play. In their head-to-head matchups, the Spurs were a massive +12.7 with Fox on the floor and plummeted to a -8.1 when he sat.
Conversely, the Spurs were +19.4 when Stephon Castle was off the floor. Castle could be a net-negative every game, but if the Spurs win, the voters won't notice the on-off splits; they will just look at his raw point totals and hand him the Western Conference Finals MVP.
Fox has played like the old man in the room this postseason, slowing things down and handling the ball securely. I'm much higher on Fox and Castle because they thrive in uncomfortable, physical environments. While I think OKC is the better overall team, the regular-season gap did not exist.
Series Picks & Best Bets
Matt Moore's Best Bets
Oklahoma City Thunder -1.5 Games on the Series Spread (-110): My model prices this closer to -123. The Thunder are the more complete team and are well-positioned to close this out in six games or less.
Stephon Castle Western Conference Finals MVP (70-1 at DraftKings): If San Antonio pulls off the upset, Castle's scoring volume and defensive assignments on Shai will catch the eyes of the narrative-driven voters.
De'Aaron Fox Western Conference Finals MVP (100-1 at DraftKings): His downhill capability and floater touch perfectly counter OKC’s defensive coverage. At a triple-digit price, it's a mandatory value play.
Brandon Anderson's Best Bets
Thunder to Win the Series From Behind (+325 at Bet365): A calculated play on Oklahoma City navigating early road adversity or a Game 1 blow before their historic home-court edge takes over. The Thunder are a ridiculous 15-2 in their last 17 home playoff games with a historic +343 point differential. I expect them to protect home floor.
Stephon Castle vs. Chet Holmgren Head-to-Head Series Points (Even Odds / -110 at DraftKings): This is my favorite bet of the entire series. Chet completely struggles against Wembanyama's size, averaging just 10.5 points per game against the Spurs this year. Meanwhile, Castle has cleared 20 points per game across both playoff series this season and averaged 21 against OKC in the regular season. This is heavily mispriced.
Stephon Castle 15+ Points Every Game (+900 at The Score): He has scored 15 or more in 10 of his 11 playoff games this year, with the only miss being a 13-point performance. He hit this threshold in four of five games against OKC.
Stephon Castle to Average 2+ Three-Pointers Per Game (+900 at DraftKings): The Thunder defense explicitly sags off specific shooters to clog the paint. Castle shot 44% from deep in the previous rounds and is averaging 2.2 and 1.8 triples per game by series.
Stephon Castle Series Threes Leader (70-1 at DraftKings): A flyer to cap off the escalator. He trails only Devin Vassell (+220 at FanDuel) in projected volume but sits second in total makes this postseason.
Long-Shots
AJ Mitchell Series Points Leader (200-1 at FanDuel): If San Antonio throws the kitchen sink at Shai and forces the ball out of his hands, Mitchell has shown the explosive scoring capability to lead the team in scoring chunks.
Dylan Harper Series Assists Leader (150-1 at The Score): Harper averaged a clean four assists per game against OKC in the regular season. With potential assist numbers tightly bunched among the guards, this market is entirely volatile and stealable.
Lou Dort vs. Victor Wembanyama Threes Per Game (DraftKings): Wembanyama opens as a -135 favorite, but the Thunder will leave Dort open on the perimeter to fire away at will, making the underdog side a fun alt-value look at +115.
