How did the Spurs get here?

When San Antonio drafted Wembanyama ahead of the 2023-24 season, they signed onto what felt like an inevitable timeline to be one of the NBA's best teams. That version was fully realized in Year 3 with the Spurs winning 62 games to secure their first playoff berth since 2019 - and it isn't just Wemby's work leading the way for the No. 2 seed.

Sure, the likely MVP runner-up has been sensational: he's averaged 25 points, 11.5 rebounds, and a league-leading 3.1 blocks while ranking third in PER (29.9) and fourth in win shares per 48 minutes (.257). That's relevant ahead of his first postseason: Wembanyama ranked outside the top 100 in minutes played this season but could theoretically be "unleashed" with a greater workload in the playoffs.

The Spurs likely won't need it, though, as De'Aaron Fox (18.6 PPG), Stephon Castle (16.7 PPG), and Devin Vassell (13.9 PPG) comprise arguably the best backcourt in basketball on both ends of the court. San Antonio was the only team ranked in the top three in offensive rating and defensive rating in the regular season, winning 19 of its final 22 games entering the first round.

How did the Trail Blazers get here?

Portland is playing with house money with longtime franchise star Damian Lillard watching from the bench with his return expected next season. This year was supposed to be a gap year of sorts for the Blazers, but Avdija (24.2 PPG, 6.9 RPG, 6.7 APG) developed into a legitimate All-Star with sophomore big Donovan Clingan (12.1 PPG, 11.6 RPG) taking another leap forward as the team's franchise center.

The Blazers clearly have a Lillard-sized hole in their lineup, but their depth sneaks up on you: Jrue Holiday and Jerami Grant are capable two-way players with playoff experience; Toumani Camara is an All-Defense wing with size and shooting; Shaedon Sharpe and Scoot Henderson can both create their own shot. It's a committee approach for a team that won 11 of its final 15 games including that see-saw affair against the Suns in the play-in.

Former Spurs player and interim coach Tiago Splitter has pieces to work with in his first playoff run as a head coach, but it's a daunting task to expect anything more than a competitive series from this group.

Who's healthy and who's hurt?

Wembanyama missed 17 games this season, including all three meetings with Portland, but played just enough games (and minutes) to qualify for awards. He's expected to be back in a full capacity for this postseason, but his status is worth following at the very least given his uncertain end to the regular season.

Grant missed seven games with a calf injury but returned for the play-in and should be good to go for the Blazers.

Who decides the series?

Any series with Wembanyama will be decided, for better and for worse, by his health and performance. If he's on the court and playing at his peak capacity, it'll be hard to beat the Spurs in any 40-minute setting, let alone across seven games.

Portland's entire game plan revolves around how to generate offense around Wembanyama's defensive orbit and how to wall him off from easy paint buckets without giving up the easy triple. Do the Blazers throw bodies at him and force the other Spurs to step up, or cut off Wemby's release valves and tax the two-way star across seven games? We haven't seen how Splitter's staff would answer that yet; we should learn a lot in Game 1 from how the Spurs use Wemby and how the Blazers counter.

Series prediction: Spurs in 6 games (+525)

San Antonio should advance in this matchup, but I think Portland makes it a series. The Blazers have the type of length and depth to throw defenders at Wemby and force him to work across what will likely be an extended workload in the postseason, and their arsenal of role players can steal a game or two at Moda Center in the first series there since 2021. I'd be pretty shocked by a series upset, but the Spurs will need to earn it.

Series prediction: Spurs to win series 4-2 (+525 via Caesars)

Best bet: Donovan Clingan rebounds leader (+140)

I get why Wemby is the favorite in this market, but Clingan ranked third in the NBA in rebounds per game (11.6) - one spot higher than Wembanyama (11.5) - and led the league in total rebound rate (23.1%) and offensive rebound rate (17.7%). The 7-foot-2 center lives in the paint in a way that the Spurs' do-it-all star simply can't if he wants to stay effective on both ends across 30-plus minutes. I love the value here on arguably the best rebounder in the league.

Best bet: Donovan Clingan to lead series in rebounds (+140 via bet365)
