Best bets on Monday, May 18

Game 7 between the Canadiens and Sabres will take place in Buffalo, which actually might help Montreal more than the home team. The Canadiens have gone 5-2 on the road in these playoffs, winning Game 1 and Game 5 in Buffalo. The Sabres are just 2-4 at home in the postseason. The SportsLine Projection Model likes these teams to combine for Over 5.5 goals, which hits in 61.9% of simulations for an "A" grade. The model doesn't have a strong spread or money line lean.

Jalen Williams is off the injury report for the Thunder, who have not lost yet in the 2026 NBA Playoffs as they attempt to get back to the NBA Finals. They'll have to go through the Spurs, who took four of the five matchups between these teams in the regular season if you include an NBA Cup semifinal. The SportsLine model believes these two defensive stalwarts will show up in Game 1, as the Under on 220.5 occurs in 60.1% simulations. Click here to bet on Canadiens-Sabres Game 7, NBA and more on Monday by signing up for BetMGM with the bonus code CBSSPORTS:
