CHARLOTTE — Luke Walton was named the Western Conference Coach of the Month on Tuesday, an announcement from the NBA that might seem obvious were it not for the fact that the Warriors’ interim head coach has yet to win a game.

Sure, the Warriors are 19-0 — the best start in NBA history — but those victories are being awarded to head coach Steve Kerr, who is on a leave of absence while recovering from two offseason back surgeries (one of which resulted in a spinal-fluid leak).

The NBA clarified its rules Tuesday, saying the head coach of record will continue to be credited with a team’s wins and losses, but that any head coach, interim head coach or acting head coach is eligible to be recognized with league coaching awards.

Kerr has said the policy of not awarding wins and losses to interim coaches is “ridiculous,” but said he answered the question before knowing the history that created the precedent. Once he learned why the rule was created — stories like that of Don Nelson, who would be dropped from the No. 1 spot among the league’s all-time winningest coaches if the handful of games he missed were credited to an interim coach — Kerr rescinded his “ridiculous” comment.

“It is a complicated issue, but in the end, it really doesn’t matter,” Kerr said. “I don’t really care. Luke doesn’t really care. We’re just happy for the opportunity to coach these guys. We can argue all we want about who should get the wins, but really, it’s the players who are doing all of the work.”

Walton said Kerr should be Coach of the Month, because the Warriors are running his system and feeding off the climate he created as the Warriors won the franchise’s first title in 40 years last season.

Walton, 35, whose meteoric rise took him from first-year assistant to lead assistant to interim head coach in a span of a couple of months, does run a lot of Kerr’s schemes and relies on Kerr’s core values for the team. Walton also has proved adept at adjusting.

“I was nervous, because this is uncharted territory for me as to how (the players) would respond to an assistant coach taking over — whether or not they would listen or whether or not they would work hard,” said Walton, who had become a confidant to many of the players last season and is now having to have to more serious head-coach conversations. “They want to win, and they’ve been absolutely phenomenal.”

Walton has had to deal with Andrew Bogut missing six games with a concussion and then having to identify the correct time to put the center back in the starting lineup after playing him off the bench for four games.

Now, Walton is tasked with replacing Harrison Barnes, who is out with a sprained left ankle. Walton had to find a starting small forward (Brandon Rush had 16 points Saturday), a backup power forward (time currently being split among Andre Iguodala, James Michael McAdoo, Marreese Speights and Jason Thompson) and a versatile defender for the team’s small-ball unit (Ian Clark scored 12 second-quarter points Monday, and Shaun Livingston made his first three-pointer with the Warriors among nine points Monday).

“One, you don’t want to let down the players, and two, you don’t want to let down Steve,” Walton said. “He put a lot of trust in me, not only to promote me to first assistant, but also to trust me with the team that he created here.

“Obviously, there’s a lot of responsibility there, and it’s nice that we’re playing so well and winning games, so he doesn’t have to stress any extra on the team. He can focus on getting healthy.”

Walton says he hears it from fans when he is slow to call timeouts, choosing instead to have the players work through the adversity together. He hears it when the fans want Stephen Curry plugged back into the lineup before his planned six-minute rest is complete.

The interim head coach said he’s willing to make adjustments on those principles, and any others, if the Warriors lose a string of games. But it’s hard to argue with the results so far.

Walton has guided the team to the NBA’s best-ever start, and the Warriors own the third-longest win streak in league history (23, counting the final four from last season) — trailing only the 27 won by the Heat in 2013 and the Lakers’ 33-game run in 1971-72. They’ve won a franchise-best 28 consecutive regular-season home games and nine straight on the road, one shy of the franchise mark.

“I’m thrilled watching our play and to watch individual players succeed,” Kerr said. “It makes me happy, but it’s also very, very difficult, because I’m not there. Just being part of the team is something I miss. There’s no question that there’s part of me that feels I’m missing out, and that’s frustrating.”

Kerr said his back feels fine, but he’s still having headaches and other side effects from the surgeries. He said there is still no timetable for his return.

“When I feel better, I’ll come back and coach,” Kerr said. “...That’s the hardest thing: You don’t know when you’re going to feel better.”
