Dylan Harper was supposed to be a bench rookie soaking up his first Western Conference Finals from the second unit. Instead, the second overall pick in the 2025 NBA Draft was thrown into the starting lineup an hour before tip-off, told De'Aaron Fox would not be playing because of a sore ankle, and asked to help the San Antonio Spurs win Game 1 on the road in Oklahoma City.
He responded with 24 points on 20 shots, four assists and the composure of a player a decade older, helping San Antonio steal the opener 122-115 in double overtime.
NBA on NBC's postgame crew was still processing what they had just watched when Harper walked over for his on-court interview. "Dylan Harper, when you talk about a rookie, you're talking about somebody who's 20 years old, the number two pick," Vince Carter said on the broadcast, marvelling at a player who had only four starts in the regular season heading into the game. "You're talking about somebody who's coming here Game 1 of the Western Conference Finals with no fear, actually putting his team on his back, taking over. Fox being injured and being out, when we talked about Fox, we thought that was a major asset to this team. But Dylan Harper stepping up and doing what he did. For me, eight for 20 as a rookie in Game 1 of the Western Conference Final tells me a lot. It tells me a lot that coach got a lot of confidence in you, Dylan."
The most telling moment came when Harper was asked when he discovered he would be starting. His answer was almost comedic in its understatement.
"About 60 minutes on the clock," Harper said.
Asked how he reacted, he gave a two-word reply that captured the night in a sentence.
"Let's go. Next man up. Let's go. Let's go. Let's go get a win."
The Spurs needed every bit of that mentality. Stephon Castle finished with 11 turnovers — and 11 assists for a strange double-double — and the inexperience of San Antonio's young backcourt nearly cost them late. Without Fox's calming presence, the Spurs leaned on Harper for downhill rim pressure, particularly out of timeouts. When asked how he stayed in attack mode, Harper credited the simplicity of his approach.
"I think it's being me," he said. "Going in the game and just being in attack mode no matter what. If shots fall or not, just keep on going and going."
The stakes were not lost on him, but the calm he projected was. Pressed on who steadied him before the biggest game of his career, Harper rattled off a list of teammates and coaches who pulled him aside.
"Really everyone. I think Fox pulled me to the side, Rashad pulled me to the side. Little bit of everyone. Mitch talked to me right before the game and just told me be me, be confident, and just keep doing what I'm doing."
The Mitch he referred to is Spurs interim head coach Mitch Johnson, the 36-year-old who has guided San Antonio through their first conference finals run since the Tim Duncan era. Johnson trusted Harper to take 20 shots — including several deep into both overtimes — on a night when San Antonio's starting lineup featured no one over the age of 25.
Harper also addressed the broader question many in San Antonio had asked when the franchise spent the second overall pick on him last June, given that the Spurs had just acquired Fox at the trade deadline.
"I think a little bit of both," he said when asked whether Game 1 was about proving the doubters wrong. "I think it was me proving to myself why I belong on this court. We talked about this before I got drafted. It was more of Fox is a great point guard. He's going to help me and teach me. And I think that him teaching me the whole season and me kind of stepping into this role tonight, I'm thankful for it."
Fox's status for Game 2 in Oklahoma City is now the most important question of the series. If the ankle keeps him out again, the Spurs have one piece of evidence to lean on: an hour's notice was all their 20-year-old rookie needed.
