While the Portland Trail Blazers threw intrigue into the mix with their Game 2 win, the San Antonio Spurs have restored order to the proceedings in this first round.

My Trail Blazers vs. Spurs predictions and same-game parlay expect the series to end in five games, thanks, in part, to Stephon Castle on Tuesday, April 28.

Our best Trail Blazers vs Spurs SGP for Game 5

The San Antonio Spurs struck gold when they had the No. 1 pick three years ago, drafting Victor Wembanyama. They were bolstered when De’Aaron Fox forced his way to their roster in a trade last season. But the piece that may make San Antonio a long-time force came in the 2024 draft, snagging Stephon Castle at No. 4 overall.

He may be the perfect complement to Wembanyama, able to score on his own but also excelling at facilitating for others.

Castle’s scoring has come in handy in this series, scoring at least 16 points in each game and averaging 21.8 points per 34 minutes.

That is an odd stat, but it is an intentional one. When Castle has played at least 34 minutes, he has cleared this points prop. When the Spurs have led by so much that he can rest easy, he has not.

But facing elimination, the Portland Trail Blazers should force San Antonio to stay engaged through much of the fourth quarter, no matter the Spurs’ lead. That does not mean the game will tighten, simply that Castle will play plenty to again score 20+ points while continuing to shoot 42.9% from deep in this series.

Douglas Farmer spends his days thinking about college football and his nights thinking about the NBA. His betting habits and coverage follow that same pattern. He covered Notre Dame football for various outlets from 2008 to 2024, most notably spending eight seasons as NBC Sports’ beat writer on the Irish. That was also when his gambling focus took off. Knowing there were veteran beat writers with three decades more experience than he had, Douglas found his niche by best recognizing Notre Dame’s standing in each year’s national landscape, a complex tapestry most easily understood and remembered via betting odds.

In 2021, that interest created a freelance opportunity with Covers, a role that eventually led to Douglas joining the company full-time in 2023. In the fall, Douglas will place five or six dozen bets each week, a disproportionate amount via BetRivers because the operator tends to have lines slightly different than the rest of the market. The same can be said of Circa Sports’ futures markets.

While Douglas is an avid NBA fan and covers the league throughout the year, the vast majority of his bets are on college football, because that is the biggest key to sports betting: Know what you do not know.
