The top of the Western Conference continues on its pace toward a Western Conference Finals matchup that we could see for many years to come.

The San Antonio Spurs suffered a brief hiccup against the Portland Trail Blazers, but my Trail Blazers vs. Spurs predictions and these NBA picks expect the series to end in five games on Tuesday, April 28.

Trail Blazers vs Spurs prediction

Trail Blazers vs Spurs best bet: Stephon Castle Over 17.5 points (-110)

However far the San Antonio Spurs advance in these NBA playoffs, enjoy Stephon Castle’s further emergence in each round. The second-year guard is considered the third banana for the Spurs, behind Victor Wembanyama and De’Aaron Fox, but Castle may actually be the most fun player on the roster.

He makes everyone else better while also pushing the pace himself and is capable of hitting just about any shot.

Castle has cleared this points prop in only two of the four games in this series, but the two games in which he fell short still featured 17 and 16 points while San Antonio won so handily that Castle’s minutes were a bit shortened.

There should be no such cruise control in Game 5. The Spurs can dispatch the Portland Trail Blazers. They should play with that clinching mentality; Castle can rest this weekend. Furthermore, Portland should go down swinging; a 20-point lead will still require protecting in the fourth quarter.

Let’s put it this way: Castle has cleared this prop in every game he has played at least 34 minutes in this series. Per 34 minutes, he is averaging 21.8 points. With a chance to win a postseason for the first time in San Antonio since 2017, expect Castle to play at least 34 minutes.

Trail Blazers vs Spurs same-game parlay

First of all, Castle has hit 9-of-21 shots from beyond the arc in this series, 42.9%, and cleared this prop in three of the four games. He is very much a shooter, and that only raises his scoring ceiling.

Second of all, it may seem counterintuitive to bet on Castle’s props because he should play a full workload tonight to clinch the series and then still expect a blowout, but those are actually hand-in-hand thoughts. Portland should press until the very, very end. That does not mean the game will get closer.

Our "from downtown" SGP: Quickly, Spurs

The Spurs should want to put this series to bed more than a team normally would up 3-1. Victor Wembanyama may be back on the court, but rest will help him recover from his Game 2 concussion.

His shot did not look great in his Game 4 return, though he did find 12 rebounds in only 34 minutes.

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.
