San Antonio's beat writers spent the week on Keldon Johnson's extension math, a crowded backcourt, and how far Wembanyama and Castle can carry the ceiling. None of it moves a 0-0 record, but most of it lines up with minutes and numbers already on the board.

What extension could Keldon Johnson get this summer?
Paul Garcia of The Spot Up Shot mapped out San Antonio's extension options for Keldon Johnson, ranging from a short bump to a four-year deal at non-taxpayer mid-level money. Johnson averaged 13.2 points last season on a $17.5 million salary and enters his final contract year with the Spurs sitting $2.1 million shy of the luxury line. Air Alamo's Ty Small called Johnson's decision-making the swing factor for what he's worth next.
Is there real tension between De'Aaron Fox and Dylan Harper?
Air Alamo's Maxwell Ogden and Cal Durrett both framed Fox and Harper as rivals for backcourt minutes, while Pounding The Rock's Jeje Gomez floated Fox starting with Harper as sixth man. The numbers back the premise: Harper has added eight minutes a night and set a 25-point career high over his last three games. Ty Small also pitched a three-guard look, with a healthy Jones Garcia, clearing an ankle issue by Oct. 8, as another option.
What are people saying about Wembanyama and Castle heading into camp?
Air Alamo's Jahlil Williams pushed back on ESPN calling Wembanyama's on-court temper immature, while Cal Durrett wrote that the Spurs' championship hopes hinge on Stephon Castle growing into the two-way wing Kawhi Leonard once was. Castle backed that up last season with 16.7 points and 7.4 assists in his second year, while Wembanyama averaged 25.0 points and 11.5 rebounds with the league's third-best defensive rating. Keldon Johnson's praise of rookie Tarris Reed Jr. adds another frontcourt name.
Has San Antonio named any coaches beyond Mitch Johnson?
KENS 5 reported Austin's G League coaching staff is set, the next step after Chris Kent was named that affiliate's head coach on Sept. 12. KENS 5 separately quoted a 'Spurs' Billy Donovan' on persistence in chasing head-coaching goals, without specifying a title, and no such name appears anywhere else in San Antonio's reported staff, so the role stays unclear.
Is Keldon Johnson getting an extension before the season starts?
Nothing is signed. The Spurs have until June 30, 2027 to extend him, and Paul Garcia's reporting only sketched the dollar ranges on the table.
Is Dylan Harper taking over for De'Aaron Fox in the starting lineup?
No change has been reported. Pounding The Rock suggested Harper as a sixth man behind a Fox-led backcourt, but that is a proposal, not a decision.
