Keys to Thunder vs. Spurs Matchup
The first two games of this series were both emphatic swings from both teams, landing on each side as San Antonio stole a road win in the opening game of this series. OKC won Game 3 to flip the momentum, so this Game 4 will be the most crucial game of San Antonio’s season thus far. Given their tired legs and inability to win as favorites during Game 3, it’s surprising to see the Spurs favored in this must-win game.
It was Thunder’s Jared McCain (26 pts), Jaylin Williams (18 pts), and Alex Caruso (15 pts) who made all the difference for their team in Game 3, hitting big shots in crucial junctures of the game and providing defensive stops. San Antonio was never really able to swing the momentum in their favor thanks to Williams’ 5-6 night from three in relief of Jalen Williams. With the aforementioned Williams on the injury report, it’ll be interesting to see if he’s able to make the start and how their offense changes with him back in the lineup.
With this being a must-win game, Victor Wembanyama is expected to play with an added ferocity and hunger to rebound the ball and block shots. He already has nine total blocks throughout this series and doesn’t seem phased at all by the defensive matchup against Chet Holmgren and Isaiah Hartenstein . He’s made a concerted effort to hit from three with a 5-12 mark over the last two games, but expect Wembanyama to get back to the paint and earn his keep at the free throw line.
Aside from the obvious, De’Aaron Fox , Stephon Castle , and Devin Vassell will need to ramp up their defensive efforts against Shai Gilgeous-Alexander once again. They managed to hold him to 24 points on 7-23 shooting in Game 1, so the key will be stopping OKC’s MVP talent and hoping that his supporting cast won’t erupt for another huge total off the bench. Otherwise, there isn’t much the Spurs can do when OKC is shooting 48% FG and 45% 3-PT.
Thunder vs. Spurs Prediction and Pick
This game will have to be a “put up or shut up” game for the San Antonio Spurs. They clearly have the recipe for beating Oklahoma City, but it’s going to take 48 full minutes of hard-pressed, highly motivated defense to beat them in the playoffs. The Thunder clearly hit another gear when in the playoffs and their depth shows most during these key games during a series.
Still, I expect Victor Wembanyama to motivate his team as we should see much more improved performances out of Castle and Fox in this one. Devin Vassell has been playing with a high motor and great effort, so expect that to carry over for Castle and Fox as they try to shut down Shai Gilgeous-Alexander.
For our final prediction, we’re going to roll with the San Antonio Spurs to cover the spread and even this series at home.
Final Thunder-Spurs Game 4 Prediction & Pick: San Antonio Spurs -2.5 (-110); OVER 218.5 (-110)
