Castle’s veteran presence could anchor the guard rotation if Harper starts or comes off the bench. His orchestrating will be pivotal for early-season efficiency, particularly in pick-and-rolls with Wembanyama and Harper's burst creating reliable spacing.

Castle, a standout rookie, is viewed as high-variance; most rookies don’t deliver fantasy impact right away, though Castle’s talent could translate into future value.

<p>Castle’s High Score fit comes from a steady baseline of points with strong defensive plays and secondary playmaking. His 1.13 High Score FPPM on 81 games last season signals upside as he absorbs a larger workload with Fox unavailable.</p><p>He isn’t a high-volume scorer in standard formats, but his ability to contribute steals and assists makes him a guarded sleeper in deep leagues, especially if his minutes grow early in the season.</p>

Castle earned Rookie of the Year considerations and could push for more starts with Fox/Hop injuries; his points and assists provide early-season upside despite efficiency concerns.

Castle joins a guard-heavy backcourt alongside Harper and Fox, bringing playmaking to the Spurs’ core. His development will influence how quickly San Antonio distances itself from the risk of overloading the backcourt and how rapidly the team can build a cohesive core.
