The Oklahoma City Thunder enter the 2026 postseason as the defending champions and the Western Conference’s 1-seed, facing a Phoenix Suns squad that just survived a chaotic Play-In path.

Thunder vs Suns Series Preview, Predictions
The Series Best Bet: Thunder to Sweep 4-0 (+130)
Matt Moore: I’ll give you my 10-word outlook right now: "We are sure this is a sweep. It’s stupidly obvious."
I know betting sweeps is usually a terrifying proposition because of NBA variance—teams get lazy, a random role player hits six threes, or a team just has a night where they play for pride.
But this Oklahoma City team is different. They aren't at the stage of their life cycle where they get fat and lazy on success. They’re too young, too hungry, and too fresh. They don't want to go home; they want to compete and beat you into the ground.
The Suns aren't built for the gear OKC can hit. Phoenix survived the regular season, but they don't have the peak level necessary to take a game off a fully optimized Thunder squad.
When you look at the matchup, Phoenix's offense is drawing dead. They are terrible at twos against an elite two-point defense, they don't get to the free-throw line, and the Thunder simply don't foul.
Brandon Anderson: I make the fair price for a sweep closer to -142, so getting +130 in the market is a massive edge. I’m a disciplined bettor—if the model shows value, I fire.
The question you have to ask is: if OKC goes up 2-0 at home and then takes Game 3 on the road, does Phoenix roll over? I think the answer is yes.
We’ve avoided betting Celtics sweeps for years because they let teams hang around, but the Thunder have a "foot on the throat" mentality.
Even with guys like Ajay Mitchell and Jaden Ivey missing time during the year, OKC still skated to the 1-seed. Now they’re healthy and rested.
Shai Gilgeous-Alexander is just better this year—more precise, never rattled, and a stone-cold killer in the clutch. I expect them to end this quickly.
Series Prop: Devin Booker Assist Leader
Matt Moore: If there’s one variance window for Phoenix, it’s the three-point line, but I think the better way to play that is through Devin Booker’s passing.
This is going to be the "Shai free throw" series in terms of the national dialogue, but the real story is how the Thunder scheme their defense. They prioritize contesting the effective field goal percentage and protecting the paint, but that results in them giving up the 9th highest assist percentage in the NBA.
The Thunder are going to throw bodies at Booker—Dillon Brooks (please don’t hurt anyone, Dillon), Lu Dort, and Cason Wallace—to pressure him and contain his scoring. When that happens, the Thunder sink down and dare the shooters to beat them.
Booker is going to have to be a primary facilitator just to keep their heads above water. He had high-volume assist games against OKC in the regular season because he has to kick to the open man once the defense collapses.
Even if the Suns’ shooters miss—and they will miss—the volume of potential assists for Booker is going to be through the roof.
If Phoenix is going to keep any of these games within 20 points, it’s because Booker is finding Royce O’Neale or Colin Gillespie in the corners.
I’ll be on Booker’s assist over for Game 1 and betting him as the series leader.
Series Prop: Royce O’Neale 3-Point Leader
Brandon Anderson: I’m looking at the other end of those Booker passes. I’ll be looking for Royce O'Neale to be the series leader in 3-pointers once the odds post.
We know the Thunder’s defensive book: they are elite, but they are willing to concede the corner three—statistically the most valuable shot outside of a dunk—more than any team in the league. They allowed the single most corner threes per game this season.
Royce O'Neale is exactly the type of guy who benefits from that scouting report. He’s a 39% career shooter who isn't afraid to let it fly, and in three games against the Thunder this year, he put up 8, 10, and 11 attempts.
The Thunder are going to scheme to leave him open to focus on Booker.
If the Suns are going to steal a game, it’s because the three-point variance swings their way for 48 minutes.
Royce is going to get the looks; it’s just a matter of whether he knocks them down.
