The Spurs’ backcourt is packed with talent, and that’s exactly why Stephon Castle’s rise feels so important. With San Antonio heading into its second season with this group, there’s plenty of buzz, a little skepticism, and a whole lot of reason to think Castle is the guard who could separate himself most clearly by 2027.
Castle already put together a huge first two years. He won Rookie Of The Year in 2025, then followed that with an even stronger sophomore season that showed off the full range of his game. Now the expectation is that his third year brings another step forward - enough to put him in the All-Star conversation and maybe make that case hard to ignore.
What makes Castle so intriguing is how much he already does for the Spurs. He handled a major load as the team’s lead playmaker last season and finished first on the roster with 7.4 assists per game, a big jump from his 4.1 assists per game as a rookie.
That kind of growth matters, but the playoffs also gave him a sharper lesson in what still needs cleaning up. His decision-making wasn’t always sharp, and the turnovers piled up.
That’s the next layer for him. If Castle tightens up with the ball, his offensive value goes up another level.
He’s already functioning as a lead guard, but the difference between good and great at that spot often comes down to how well a player handles those high-pressure possessions. If he makes that leap, he moves from solid to elite in a hurry.
The same kind of progression could show up on defense. Castle didn’t earn an All-Defensive team spot last season, but his impact was impossible to miss, especially in the playoffs when he did a strong job on some of the league’s best perimeter scorers, including Shai Gilgeous-Alexander in the Western Conference Finals.
The next step is cutting down on foul trouble, which kept showing up in the playoffs. If he can stay aggressive without crossing that line, his defense gets even more valuable.
That’s what makes Castle so different in a Spurs backcourt that also features Harper and Fox. Those two are dangerous shot-makers and constant pressure points at the rim, but Castle brings a broader package.
He scores, he passes, he defends, and he already looks like one of the league’s best point-of-attack defenders. Put all of that together, and you get a guard whose All-Star case in 2027 should be very real.

Spurs Linked To Veteran Frontcourt Move That Would Change Everything Around Wemby
San Antonios offseason watch already has a familiar shape: the Spurs are looking for ways to keep building around Victor Wembanyama, and any frontcourt addition will be judged through that lens. With cap flexibility on their side, the team has room to explore a move that could add more size, athleticism and experience to a young core that is still taking form.
One name that keeps surfacing in that conversation is John Collins, with Chicago also frequently mentioned as a potential landing spot. The appeal is obvious on paper, since Collins could offer a different kind of presence next to Wembanyama, but the fit is not without questions because of his inconsistent shooting and only average rim protection.

Spurs Have A Sneaky Chance To Add Another Defensive Menace
The Spurs have spent plenty of time looking for ways to sharpen the edge of a defense built around Victor Wembanyama, and Jonathan Isaac fits the kind of low-risk swing that can be easy to picture from afar. Waived by Orlando and now on the market, he brings the sort of defensive reputation that has kept him on radars even as his value has been dulled by injuries and uneven availability.
The appeal is obvious on paper, because Isaac has long flashed the ability to change the tone of a game when he is healthy and engaged on that end. The hesitation is just as clear, since his offense has never come close to matching his defensive upside, which leaves any pursuit feeling speculative rather than certain for a Spurs team that is still weighing how much it wants to gamble on another high-upside, high-variance piece.

Spurs Suddenly Have A Franchise-Changing Path To Speed Up Wembanyamas Timeline
For a franchise still trying to compress Victor Wembanyamas ascent into something more immediate, the idea of adding a proven star has a certain logic. That is why the chatter around a possible LeBron James sign-and-trade has landed with such force, especially with Bill Simmons and others floating the notion that a veteran of his stature could bring both on-court stability and the kind of locker-room gravity young teams usually have to wait years to find.
The financial side would be delicate, and the roster fit would have to make sense for both sides, but the appeal is obvious from San Antonios perspective. A lineup built around DeAaron Fox, Stephon Castle, Devin Vassell, LeBron and Wembanyama would instantly change the temperature around the Spurs, while the Lakers would only consider such a move if they believed the return helped them elsewhere. The question now is whether this is just offseason noise or something the Spurs can seriously treat as a path worth exploring. [Read more 🡒]
