The Thunder need to get Shai Gilgeous-Alexander going. Adjusting his minutes could be the spark.

How the Oklahoma City Thunder adjust to their Game 1 loss to the San Antonio Spurs should be the most intriguing part of Game 2. That conversation can start with Shai Gilgeous-Alexander, whose impact is altered by overlapping so many minutes with Victor Wembanyama.

These Spurs vs. Thunder predictions dive into the Shai Gilgeous-Alexander odds and will not bet on the two-time MVP staggering his minutes entirely away from the Defensive Player of the Year, though that is an adjustment worth pondering for Game 2 tonight.

Shai Gilgeous-Alexander prop pick for Game 2

Shai Gilgeous-Alexander best bet: Over 28.5 points (-105 at bet365)

In a game that went to double overtime and saw the Oklahoma City Thunder eventually lose by seven points, Shai Gilgeous-Alexander playing 51 minutes and posting a -15 stands out.

It is not a coincidence that San Antonio Spurs superstar Victor Wembanyama played 49 minutes and posted a +16.

Wembanyama is the best rim deterrent in the NBA, the best rim deterrent since... well, that historical lookback can be pondered another day.

The Thunder are deep. It is one of their greatest assets. They have the personnel to better stagger SGA into the minutes Wembanyama rests, and there should be more minutes without Wembanyama after that double-overtime effort on Monday.

Such a stagger would immediately boost Gilgeous-Alexander’s shooting; his 7-for-23 showing in Game 1 was ugly yet still yielded 24 points. Any improvement in his shooting should set up the MVP to reach 30 points in what is effectively a must-win for OKC.

Wemby’s rim presence often turns drives into passes, part of how Shai Gilgeous-Alexander managed 12 assists in Game 1. Just as vitally, the MVP’s teammates showed up. The Thunder shot 17-for-45 (38%) from deep, boosted by Alex Caruso’s 8-for-14 mark.

Even if (when) Caruso’s shooting tails off, SGA’s assist numbers should still be near double digits all series long. Wembanyama’s rim presence demands that.

Simply put, Gilgeous-Alexander needs to do a bit of everything in this series, as he often has to for the Thunder. That is the burden of being a ball-centric MVP.

He will need to find his moments to preserve some energy, and that should come on the glass. Gilgeous-Alexander grabbed only three rebounds in 51 minutes in Game 1. Credit Wembanyama. Credit Stephon Castle. Credit Dylan Harper.

Also realize it is somewhat prudent of SGA to sacrifice some rebounds in the name of playing aggressive defense and dictating OKC’s offense.

Douglas Farmer spends his days thinking about college football and his nights thinking about the NBA. His betting habits and coverage follow that same pattern. He covered Notre Dame football for various outlets from 2008 to 2024, most notably spending eight seasons as NBC Sports’ beat writer on the Irish. That was also when his gambling focus took off. Knowing there were veteran beat writers with three decades more experience than he had, Douglas found his niche by best recognizing Notre Dame’s standing in each year’s national landscape, a complex tapestry most easily understood and remembered via betting odds.

In 2021, that interest created a freelance opportunity with Covers, a role that eventually led to Douglas joining the company full-time in 2023. In the fall, Douglas will place five or six dozen bets each week, a disproportionate amount via BetRivers because the operator tends to have lines slightly different than the rest of the market. The same can be said of Circa Sports’ futures markets.

While Douglas is an avid NBA fan and covers the league throughout the year, the vast majority of his bets are on college football, because that is the biggest key to sports betting: Know what you do not know.
