Celtics vs. Pistons

Combo: 4.75x

  • Celtics moneyline
  • Under 221.5
  • Jayson Tatum Over 8.5 rebounds

Tom Oldfield is backing Boston to open the season with a road win, citing the Celtics' strong away record and defensive potential. 

"The Celtics were 21-6 SU as road favorites last season, and I'm picking the visitors to start the post-Jaylen Brown era with a win at Little Caesars Arena."

76ers vs. Knicks

Combo: 8.11x

  • Knicks -4.5
  • Over 231.5
  • 76ers 1H +2.5

Shawn Krest is backing the defending champion Knicks to cover, but doesn't see them getting off to a fast start.

"The Knicks produced plenty of dramatic comebacks in their run to the title last year. That's because they got off to slow starts regularly, a trend that's continued in the preseason. The wild offseason of battling off-court attention and demands could also lead to a sluggish start for New York."

See our full 76ers vs. Knicks predictions for additional insight.

Thunder vs. Spurs

  • Time: 9:30 p.m. ET
  • TV: NBC/Peacock
  • Analyst: Geoff Clark

Combo: 6.69x

  • Spurs moneyline
  • Isaiah Hartenstein 3+ assists
  • De'Aaron Fox 2+ 3-pointers made

Geoff Clark is backing the Spurs to win their home opener against the arch-rival Thunder.

"The Spurs were 8-4 straight up (SU) and against the spread (ATS) vs. the Oklahoma City Thunder with a +7.6 spread differential last regular season and in the playoffs. San Antonio also went 4-1 SU and ATS against OKC in the regular season and NBA Cup despite Wembanyama starting only twice and averaging 25.1 minutes across those five games. Now Wemby should be fully unleashed."
