Stephon Castle has already proven himself as one of San Antonio's most important players with his elite two-way impact and has also made it clear that he's one of the best second options in the entire league. But a recent ranking placed him concerningly low in the hierarchy of the NBA's top number-twos.
Ranking the top 10 best No. 2 options in the NBA:

Spurs fans should be disappointed with this listing. With all due respect to the players ranked above him, Castle's body of work last season is enough evidence alone to justify a significantly higher placement than No. 10.
Stephon Castle's already done what some of these players haven't
Last season, the Spurs pulled off one of the most unexpected NBA Finals runs of the century. They went from being one of the biggest question marks in the Western Conference to competing for a championship in one of the best series of the 2020s.
Stephon Castle was an elite second option next to Wemby throughout that unprecedented deep run, averaging 18.2 points, 6.1 assists, and 5 rebounds on 45.9% shooting and 35% from three. In an elimination game against the Timberwolves, he became the youngest player in league history to record 30+ points, 10+ rebounds, 5+ assists, and 5+ threes.
While Castle did all of that at 21 years old, several others who were ranked above him have yet to accomplish such impressive feats. Scottie Barnes, LaMelo Ball, and Alperen Sengun are great players, but they haven't performed at that high a level for a lengthy postseason run. None of them have ever even made it out of the first round in their careers.
So it begs a simple question: how could Ball, Barnes, and Sengun be better second options than Stephon Castle without matching his elite postseason production? Sure, it was just one playoff run, but still, they never reached the level he did on such a big stage.
Stephon Castle could permanently silence his doubters next season
If you're still skeptical about Stephon Castle's impact, that's fine. Maybe last season wasn't enough, but you should definitely brace yourself for the leap he'll make in the 2026-27 campaign.
There was a benefit to his NBA Finals loss: the series exposed his biggest weaknesses on both ends, giving him a checklist of things to improve on next season. We should see a version of Castle that's even more dangerous as a shot-creator, all-around scorer, and better at limiting turnovers.
Another dominant showing from Stephon won't just solidify his case as a top-five-caliber second option, but it'll help push the Spurs to another level. His progression on both ends of the floor will be important for what San Antonio is trying to accomplish: holding up the Larry O'Brien trophy for the first time since 2014.
