The Game Turned Late
The San Antonio Spurs once had a favorite playoff lever. When the season tightened, Gregg Popovich would shift Manu Ginobili from the bench to the starting five, and the message was clear: San Antonio was finished calibrating and ready to win. That move won titles. The question now is whether the same lever exists in 2025.
Dylan Harper and De'Aaron Fox present a different geometry. Both are downhill guards with inconsistent jumpers, both want the ball in their hands, and neither is a high-level shooter. Fox signed a max extension. He's an All-Star at 28. Harper is 20, the No. 2 pick in the 2025 draft, and he's playing like the better player right now.
The matchup already has enough history; the job is to keep the reading list shorter than the tension.
The Spurs won 62 games with Fox starting. That earns you the benefit of the doubt, and the coaching staff stuck with what worked. But the Finals are not the regular season. The margins are too thin for sentiment.
Harper generated 10 of San Antonio's 42 points in the paint in Game 1. The Spurs averaged over 52 in the regular season and 49 per game through the first three playoff rounds. Against the Knicks, that production cratered. Harper has been one of the best rim-pressuring guards of the entire postseason, averaging 4.7 shots in the restricted area per game and hitting 67.4% on those looks. Among true guards, only Anthony Edwards, Tyrese Maxey and Jalen Brunson have gotten to the rim more this postseason. All three play more minutes than Harper.
The Small Details Added Up
Fox, since returning from a high-ankle sprain, is attempting only 2.6 shots in the restricted area per game and converting at 46.2%. He's subsisting on jumpers and runners. When those fall, he looks like an All-Star. When they don't, the offense stalls. In Game 1 of the Finals, he shot 1-of-10 outside the restricted area.
Defensively, Harper's size matters. Listed at 6-foot-5 and 215 pounds, he's notably bigger than Fox (6-3, 185) and defends far more physically. When Harper guarded Brunson across 14.4 partial possessions, the Knicks repeatedly tried to screen him off. That's a matchup problem New York created, not one San Antonio solved.
Fox is a reasonably effective defender for a small guard, but reasonably effective still means vulnerable against Brunson. Julian Champagnie became Brunson's preferred target. The Knicks are not the Thunder; they don't force turnovers at that rate. What San Antonio needs against New York is rim pressure and defenders who can hold up on Brunson, and Harper provides more of both.
The Harper-Fox pairing worked in Game 1: plus-5 in their shared minutes. But the Spurs have resisted playing all three of their top guards together. Fox, Harper and Castle logged only 43 playoff possessions together. The coaching staff has preferred spacing over three-ball handlers, and removing Castle from the rotation is not realistic. He's too important defensively and provides his own rim pressure.
The Table Looks Different
In Game 1, Harper played four fewer minutes in the fourth quarter than Fox. He was clearly the superior player that night, but the Spurs lost anyway and surrendered home-court advantage. There are between three and six games remaining. The season does not pause for players to recover.
Popovich turned to Ginobili for the biggest games of San Antonio's first dynasty because the moment demanded it, not because the decision was comfortable. If Harper is the better player in this series, the uncomfortable decision is the right one. That's the lever. It worked before.
