The Toronto Raptors conclude their Texas road trip on Monday against Victor Wembanyama and the San Antonio Spurs.

The pregame narrative: Wembanyama's monster start to the season has the Spurs unbeaten through three games. San Antonio is favoured to win as Toronto looks to snap a two-game losing streak after falling in Dallas on Sunday.

Check out my Raptors vs. Spurs SGP predictions for Oct. 27, featuring Wembanyama and Stephon Castle.

Raptors vs. Spurs predictions

Parlay: Raptors +10.5 | Wembanyama 2+ threes | Castle over 14.5 points (+300)

Raptors +10.5 (-325): I want to start this parlay out by backing the Raptors to cover as underdogs, which they did plenty of last season.

  • Toronto was 39-29-1 as a dog last season. That was the fourth-best mark in the NBA (excluding OKC, which was only an underdog three times).
  • The Raptors are 1-0-0 ATS as an underdog so far, and have covered a +10.5 spread in all three of their games.

Buying six points on the standard +4.5 line seems pretty safe to me. San Antonio is off to a perfect start, but has faced three non-playoff teams from 2024-25.

It has only covered a -10.5 spread once — on opening night against the shorthanded Dallas Mavericks.

Wembanyama is matchup-proof and should feast tonight, but Toronto is the much deeper team here. Look for the Raptors to pick up ground during the bench minutes.

NBA SGP legs

Wembanyama 2+ threes (-149): Wembanyama has come out of the gates in MVP form. He's averaging 33.3 points, 13.3 rebounds and 6.0 blocks through three games.

The 7-foot-4 centre only attempted five 3s through his first three games, but kicked things into high gear by going 3-for-6 from beyond the arc last night.

That was more on brand with the type of basketball we saw Wembanyama play last season. In 2024-25, he averaged 3.1 threes on 8.8 attempts per game (35.2%).

Toronto has a good perimeter defence, but Wembanyama's jumper is unguardable thanks to his length. This will simply come down to the type of 3-point shot volume we'll see, and I'm betting it will be high.

Castle 15+ points (-162): Castle won Rookie of the Year honours last season thanks to a strong second half. He averaged 17.8 PPG on 43.9% shooting in 30 games following the all-star break.

The point guard wasn't efficient by any means, but also didn't have the luxury of floor spacing with Wembanyama sidelined.

Now, Castle has much more room to operate and is playing well as San Antonio's No. 2.

  • 17.0 PPG
  • 52.9 FG%
  • 30.7 MPG

Toronto has gotten torched by point guards so far, giving up 30.85 PPG to the position through three games, according to Fantasy Pros.

I like Castle's chances of reaching this teased-down milestone.
