What happened: San Antonio's move to a three-guard starting lineup featuring Dylan Harper has shifted roster questions toward the reserve unit, per Jared Weiss. While the opening five is set, the coaching staff now faces the challenge of sustaining offensive consistency once the starters go to the bench.

Why it matters: Reliable reserve production was a core strength for the club last season, and elevating Harper into the starting unit alters the balance of ball-handling across the rotation. Finding steady playmaking behind the opening group will determine how well the alignment holds up over the regular season.

What to watch: With the upcoming game currently scheduled at 0-0, how the coaching staff staggers its guards will offer the next look at the second-unit rotation.
