The current betting odds have the Spurs listed as a 6.5 point underdog in this game according to Draftkings Sportsbook. The Spurs have looked great in their games this season with their 60-22 record overall which had them right near the top of the West with one of the best records in the entire NBA. They have been a great road team too with their 29-12 road record this year. Meanwhile, the Thunder have looked great in their games this season with their 64-18 record overall which had them right at the top of the West with the best record in the entire NBA. They have looked great on their home court too with their 34-7 home record this season. This is game 1 of a 7-game series between the 1st seeded Thunder and the 2nd seeded Spurs for the Western Conference Finals of the NBA playoffs. The Thunder have been rolling in the playoffs so far. They haven't lost a game yet and they have a ton of momentum on their side with 8 wins in a row now. They are off a 5 point win over the Lakers in their last one though and now they have had a really long rest before this series which could turn to rust. The Thunder have been crushing their opponents in the playoffs this year, but the Spurs were a team that they had a lot of trouble with during the regular season. The Spurs are off a 4-2 series win over the Timberwolves in their last one and they have some momentum with 2 wins in a row now. They crushed the Timberwolves by double digits in 3 of those games too and they have shown all year that they have the talent to go toe-to-toe with the Thunder in this series. The Thunder have been rolling in the playoffs, but so have the Spurs lately and the Thunder are due for their 1st loss of the playoffs soon. The best way to place a bet here is on the Spurs to cover the spread in this game.

“Of course we’re confident, but we need to keep the right confidence level. Right now, I’m not even thinking about it. I’m just thinking about recovering.” - Victor Wembanyama after their win against the Timberwolves in game 6 of that series on Friday. 

"They won more of the minutes tonight than we did, and that hadn't been the case (earlier in the series). They outplayed us for stretches. They're a really good team with prideful players. We did not expect them to give us an unearned win, and we went out and earned it." - Mark Daigneault after his team’s win against the LA Lakers in game 4 of that series on Monday.
