The Trail Blazers are on the brink of elimination in the NBA Playoffs, but they should compete hard in tonight's game. Action Network analyst Matt Moore believes Portland has enough fight to keep tonight’s game competitive.
Trail Blazers vs. Spurs Prediction: Trail Blazers +12.5 (54%): This is a small play, but the trend is hard to ignore: Game 5 home favorites up 3–1 win 80% of the time straight up since 2003, yet they’re just 46-52-2 against the spread—and that drops to 39% ATS when favored by more than 10 points, suggesting inflated lines. With their season on the line and likely the final game for Tiago Splitter, expect Portland to come out with maximum effort and keep this one competitive.
If you place $20 in trades on the Trail Blazers +12.5 and your pick wins, you earn a $36.53 payout. From there, you can continue trading on any game or prediction market on Polymarket.
