In their darkest playoff hour, Lakers coach JJ Redick advised his players during practice Sunday to take the same mental approach for the win-or-go-home Game 4 that they’ve used since the first day of training camp.

The Lakers trail the Oklahoma City Thunder 3-0 in the best-of-seven Western Conference semifinal series. The Lakers must beat the Thunder at Crypto.com Arena on Monday night or their season is over.

“Our first slide that we put up in training camp was [to] win the day,” Redick said. “Today was a quick offensive review and then just going over some stuff defensively. Got to win today and we got to win tomorrow. We know what we’re facing being down 3-0. So it’s just more of a mindset check than anything else.”

No NBA team has ever come back to win a series when trailing 3-0, with those teams holding a 161-0 record.

Those are the long odds the Lakers face.

Redick was asked what his team’s mood was like at practice.

“These guys are good,” he said.

Redick then was asked what his squad has shown him that gives him hope the Lakers can still win.

“Affirmation,” he responded.

Even after losing three games by an average of 19.6 points per game, the Lakers still cling to some hope.

Rui Hachimura has been on what Redick called a “heater” from three-point range. He has made 57.1% of his threes and has shot 54.1% from the floor in the series, averaging 18.3 points per game.

Hachimura thought back to the Lakers’ first-round series against the Houston Rockets and how they had a commanding 3-0 lead. But the Rockets fought back to make the series 3-2 before the Lakers closed out the series.

“It’s crazy, but I think that’s the mentality we need,” Hachimura said. “I think it’s one at a time. I think especially with this type of team, you can’t really make mistakes. … We have to keep the same energy the whole game. That’s the only way we can win. So, we know what we do.”

What they need to do is play better in the third quarter. The Lakers have been outscored 92-61 in the third quarter by the Thunder.

“I feel like every game we’re getting closer,” Hachimura said. “Especially last night … apparently we had the best offensive game of the series, even the playoffs. I think we had really good looks, great looks. But I think defensively we, especially in the third quarter, we kind of slowed down. I don’t know [if] we got burned out or we got tired, whatever.

“So, I think our focus is like how we play in the first half we have to do in the whole game. … That’s going to be our goal.”

The Lakers have managed to slow down Thunder star Shai Gilgeous-Alexander by having Marcus Smart guard him and putting constant double teams on the reigning NBA most valuable player.

Gilgeous-Alexander is averaging 21.0 points per game in the series, far below the 31.1 points he averaged during the regular season. He’s averaging 5.7 assists per game, which is below his 6.6 during the regular season, and he’s shooting 45.8%, which is below his 55.3% for the season. He’s averaging four turnovers in the series as well.

But Chet Holmgren, who is averaging a double-double in the series at 21.3 points per game and 10.0 rebounds, has been a handful for the Lakers. Ajay Mitchell is averaging 20.7 points per game and 6.6 assists.

That’s why the Lakers are on the verge of seeing their season end. The Lakers have faced adversity all season, but Game 4 will be the ultimate test.

“Being on the Lakers, you feel like your back’s against the wall every game,” Redick said. “So I think the whole season has prepared us to be in a position where we’re in the second round of the Western Conference and being in the mix with a great basketball team.”

When the doors opened after Lakers practice on Monday, injured stars Luka Doncic and Austin Reaves were nearby as their teammates took some final shots after the session.

Doncic, who is back with the team after traveling to Spain to receive treatment for his Grade 2 left hamstring strain, sat out the Lakers’ Game 1 win over the Houston Rockets. He also won’t play in Game 2 on Tuesday, but he remained his usual joyful and playoff self after practice, his infectious personality providing a good vibe during a tense time for the team.

But even without Doncic and Reaves, the Lakers still had an “elevated” two days of practice as they prepared to face the Rockets with or without All-Star Kevin Durant at Crypto.com Arena.

Doncic, who sustained his injury against Oklahoma City on April 2, hadn’t been with the Lakers during their final five games of the regular season. Having him back around the team provided the Lakers with a big boost ahead of Game 1.

“It’s amazing. I think people don’t know how much impact Luka has, not only on the court, but off the court,” Rui Hachimura said. “He’s a guy that always wants to be around. … We love him just being around, just hanging out, talking. So, yeah, we’re happy that he’s back finally and he’s doing funny things always. … We missed him for sure.”

Hachimura was asked about the funny things Doncic did during practice.

“Just messing around with the coaches and the players and just the normal things you guys see on the camera, probably,” Hachimura said. “It’s just a normal thing for him.”

The Lakers weren’t messing around during the film sessions or practices.

They were focused on the task ahead, knowing the Rockets don’t want to go down 0-2 in the series.

“Well, every day requires something different,” Lakers coach JJ Redick said. “Yesterday required an elevated recovery day. Today required an elevated focus. It was a longer film session. A decent amount of teach [and] talk on the court beyond just the practice session. Tomorrow is going to require an elevated sense of desperation on our part because they’re going to come in with that.”

Durant didn’t play in the first game because of a right knee injury and has been called a game-time decision, Rockets coach Ime Udoka told reporters after practice.

Whatever the case is, the Lakers are expecting a tough game against the Rockets.

“Yeah, I mean, it’s the playoffs. Every team’s got to play desperate,” Jaxson Hayes said. “I mean, if you lose, you go home. So, if you’re not playing desperate, then why are you here at the end of the day? But, yeah, I mean, we played against teams like this all year. I mean, obviously, they’re a very aggressive, very fast-playing, big, long team, and so we just got to make sure we take care of the ball like we didn’t do in Game 1 and just get rebounds and just stay locked in.”

With Doncic and Reaves (Grade 2 left oblique muscle strain) out, the Lakers needed other players to fill that void.

Hachimura did his part in Game 1, and it went beyond his 14 points. He was efficient from the field, going six for 10. He was good on defense, collecting three steals and two blocked shots in 42 minutes.

“It’s the playoffs. You have to make every play matter,” he said. “Every position matters. So, I was trying to make plays and not only offense, but on the defensive side. And rebound, and all that. So, that’s what I was doing.”

During Game 1, Doncic offered advice and encouragement to his teammates from the bench.

But his recent conversations with Hayes have been focused, in part, on what comes after the season.

Doncic has talked to Hayes about playing for the Slovenian national team and the big center has interest.

“Um, we got my Slovenian passport. That’s all he’s been telling me,” Hayes said. “Now he’s been saying, ‘My Slovenian brother,’ every time.”

Hayes laughed, and then was asked if he really did receive a Slovenian passport.

“Yeah,” he said, “it really came through.”

There was a moment during Game 1 when Doncic was playing around with Hachimura, hitting him on the head. But Hachimura didn’t recall it happening.

“Hmm? I don’t remember,” Hachimura said. “He always does that stuff. I probably don’t even think about it. I’m used to it, probably. I don’t remember that.”
