Stephon Castle, the San Antonio Spurs‘ reigning Rookie of the Year, came off the bench for the first time this season during their 135-123 win over the Dallas Mavericks on February 5, 2026. The decision came amid a back-to-back stretch for the Silver and Black, with Castle listed as questionable for the previous night’s game against the Oklahoma City Thunder. Head coach Mitch Johnson clarified that Castle’s bench role was part of a deliberate minutes management plan, not a reflection of his status or performance.
Coach Johnson Explains Castle’s Minutes Restriction and Role
Mitch Johnson addressed questions about Castle’s reduced minutes and revealed that the young guard was on a minutes restriction alongside teammate Dylan Harper. The intent was to carefully navigate playing time among key players to ensure their availability and effectiveness throughout the game and season.
When we’re healthy, and everybody has their minutes available, Steph will be a starter,
Johnson said.
Yeah, we had a couple of guys that were just trying to be mindful of minutes, and him and Dylan [Harper] were the two,
Johnson added.
So, it was just about trying to maximize giving guys natural flow to their minutes and making sure Steph was available for them.
Parallels Drawn with Victor Wembanyama’s Minutes Management
Johnson’s cautious rotation of Castle echoes a similar strategy used for the Spurs’ star big man Victor Wembanyama following his injury returns. Despite Wembanyama’s stature as the team’s top scorer, he has come off the bench in important games such as the NBA Cup Semifinals and while recovering from a hyper-extended knee. These adjustments allowed him to return gradually while still contributing in critical moments.
When I think of the reaction, my reaction is that it was a minute thing. I mean, it wasn’t a lineup thing,
Wembanyama said regarding Castle’s bench role.
I think it was to maximize the minutes, just like when I was coming off the bench,
he continued.
And I think that there is no better way to impact the game in just 21 minutes. He’s a plus seven, 20 plus/minus. So what (else) can we ask for?
Castle’s Impact Despite Limited Minutes Against Dallas
Although Castle played only 22 minutes against the Mavericks, his statistical contribution was significant. He scored 18 points, handed out six assists, made three steals, and collected seven rebounds. His energy and effectiveness, particularly on the defensive end and in rebounding, showcased why the Spurs view him as a vital piece of their roster.
Steph and KJ [Keldon Johnson] and Dylan, all with five, six, and seven,
Johnson commented on the rebounding effort by his wing players.
The 6-foot-6 guard, recognized as a Rising Star for a second consecutive year, has demonstrated consistent rebounding ability since entering the NBA with the Spurs in late 2024. Johnson emphasized the importance of “gang rebounding,” highlighting the collective effort that extends beyond the big men to create offensive opportunities.
Even when we have those bigs in there, we know they’re fighting off the other bigs as well. So, the gang rebounding is important.
Johnson added.
And then it also goes right into leading to our offense because all those guys can bust out on the dribbles and lead the break as well, right off the rebounds.
Spurs Surpass Previous Season’s Win Total with Victory in Dallas
Castle’s performance contributed to the Spurs securing their 35th win of the season, surpassing last year’s total. The former UConn standout connected on eight of his 13 field goal attempts while continuing to develop his role on a young and evolving Spurs squad. The coaching staff’s careful management of minutes, especially with key players like Castle and Wembanyama, reflects a focus on sustainable success as the team pushes deeper into the NBA campaign.
