Brooklyn Nets head coach Steve Nash said the return of superstar James Harden will "change everything" after the NBA championship hopefuls slumped to a fourth consecutive defeat.

The star-studded Nets – playing without former MVP Harden again due to a hamstring injury – fell to the Dallas Mavericks 113-109 on Thursday.

A game-high 45 points from Kyrie Irving and Kevin Durant's 20 points were not enough for the Nets, who are two and a half games behind the Philadelphia 76ers in the race of the Eastern Conference top seed ahead of the playoffs.

Harden has not played since April 5 but is "very confident" he will return to action before the postseason gets underway.

Reflecting on the result, Nash – whose Nets are eyeing their maiden title – told reporters: "We're just trying to get better every day. We can't really control the injuries. We're getting healthy bodies back, we've got the most guys I think we've had all year right now that are available; so that's positive. Trying to figure out some rotations and combinations.

"Obviously, James comes back at some point and changes everything again. But we're trying to just get better. We're trying to get more familiar with what we're trying to do, trying to get better at our principles and get a better understanding between one another.

"As I said, a lot of these teams have been in the last two, three, four years in a row. We're just getting to know each other; a lot of our guys have missed a lot of season. So trying to gain that understanding, that continuity is what we're after right now. We're going through a tough stretch, we're not playing really well, we're not playing really sharp. We were right in it today, we had our chances for sure; we've had our chances in the last three games.

"So what is it that can get us over the hump? I think the first thing is for us to continue to stay strong mentally, to pick each other up, to realise we got a lot of work to do. We keep working, we don't let this take the wind out of our sails and we'll improve and get better."

While Irving starred, Durant was below his best against the Mavericks as he finished seven-for-21 shooting, having missed all four of his three-point attempts on the road.

"Kevin didn't have a great rhythm tonight, especially in the second half. He normally can get to his spots and convert. He just wasn't in a great rhythm. Some nights it's just going to happen," said Nash.

"We're all going to have poor shooting performances or nights where we don't quite have a rhythm. And then the defense, we made some mistakes. I thought the third-quarter defense was really good. In the fourth quarter, we made a few mistakes and they made a few plays, but I think there's a lot to build on. We can look at the tape, continue to build, continue to grow."

Durant added: "It's trust my work and most of the times a mentality switch on what I need to do to be more effective and more efficient. Tonight I tried shots that I shouldn't have tried. I shot over a double-team in the fourth quarter. I shot a runner going to the left, just trying to get into the game scoring-wise, and sometimes that pushes me out of the game when I try those tough ones, but it's all a learning experience.

"I'm glad it's happening now for us instead of in a couple weeks, and hopefully we build off of this and keep growing, and I hope we feel this pain, I guess, from losing, feeling like we're not where we want to be. I like this position for us, and I think it's gonna make us better as we continue to keep watching film, going through practice, going through shootarounds and then playing in games."

Brooklyn Nets superstar James Harden is "very, very confident" he will return from injury before the NBA playoffs.

Harden has not played since leaving the matchup against the New York Knicks on April 5, with the star-studded Nets slipping two games behind the Philadelphia 76ers in the Eastern Conference.

Former MVP Harden – who arrived from the Houston Rockets in a blockbuster trade in January – is averaging 25.2 points, 10.9 assists and 8.0 rebounds per game this season.

Harden's assists per game – second only to Washington Wizards star Russell Westbrook (11.3) in 2020-21 – is his best mark since averaging 11.2 in 2015-16, while he only averaged more rebounds in 2016-17 (8.1).

"Very, very confident," Harden told reporters when asked about being ready for the playoffs. "I guess I have to hit the marks in the work I did today. Have a couple of those without any feeling. That's pretty much the mark. I'm very confident I'll be back before the postseason.

"The plan is to hopefully get an opportunity to play a couple games before the postseason. We're just taking one day at a time.

"So far, so good. Today was really good, and we've just got to keep building on that."

"We wanted to be patient," Harden said. "As much as I love to hoop, I want to be out there, but you've got to be smart. And for me, it was just, 'Let's knock this thing out, let's get this thing healthy so we can make a push.'"

Harden added: "At this point in my career, going to postseasons basically since I've been in Houston, I've been playing heavy minutes, just carrying the load.

"And this was an opportunity for me to keep my body right going into the postseason with a clear mind and a clear body. You've got 16 games to win. That's the ultimate goal. That's the reason why I came to Brooklyn."

The Nets boast Harden, former MVP Kevin Durant and fellow superstar Kyrie Irving but Brooklyn's big three have only played together seven times this season due to injuries and absences.

Brooklyn (43-23) have lost three consecutive games, while they own a 5-5 record in their last 10 games as Steve Nash's Nets eye their maiden championship.

Harden does not believe injuries have damaged the Nets' title charge, saying: "No, no. No. I just... no. We're sitting right now at this point [in the] second spot and we've had so many different line-ups; that right there tells you how great, good, or whatever-you-wanna-call-it this team is.

"The most important thing for us going into the postseason is health. This season has been so condensed — you see a lot of guys are going down because of the amount of games. So I think for us our mindset is, alright, if we can come to the postseason healthy, we are right there and we got a chance.

"Finish these last six games out strong, focus on the things that we need to focus on, the things we can control, and go out there and have fun and we live with the results."

A 103-101 loss to the Toronto Raptors on a buzzer-beating three-pointer just over a month ago on April 5 seemed to encompass the Washington Wizards' season perfectly.

Washington blew a 19-point, third-quarter lead en route to dropping to 0-11 when failing to score more than 102 points. It was a fourth straight loss for a team playing their fifth game in a row without 2020 scoring leader Bradley Beal, and the defeat dropped the Wizards to 17-32 – the third-worst record in the Eastern Conference and 3.5 games out of 10th place for the final spot in the play-in tournament.

The Russell Westbrook experiment was looking like a disaster and very little suggested a playoff push was possible over the season's final five and a half weeks given the team's struggles over the season's first three months when Beal was healthy.

Surprisingly, however, the Wizards didn't fold.

They showed some reserve two nights later with Beal back in the lineup, finishing strong in a 131-116 victory over the Orlando Magic after nearly blowing all of a 21-point, third-quarter lead, then escaped with a 110-107 road win over the Golden State Warriors on April 9 with Beal scoring six points in the final 6.1 seconds.

The win streak ended the next night but that was no big surprise as they were on the road against a Phoenix Suns team that is currently battling for the best record in the league, not to mention Beal sat out the second half of a back-to-back.

Since then, though, Washington has compiled the league's second-best record at 11-3, racking up 115 points or more in all 14 of those games. The only other team in the past 30 years to have a streak like this was a 20-game run by the 2018-19 Oklahoma City Thunder – a team also quarterbacked by Westbrook.

Since April 12, the Wizards are averaging an eye-popping 126.0 points per game to lead the NBA, and while Westbrook and Beal have played a big role in the scoring explosion, the offense is getting a boost from some unlikely sources thanks to a somewhat unconventional approach.

In this age of players regularly hoisting up three-point shots, the Wizards are instead focusing on pushing the ball inside.

Washington are attempting 7.1 fewer three-point attempts in their most recent 14 games compared to their first 52 contests, with their 23.4 three-point attempts since April 12 ranking fewest in the league – 3.7 attempts fewer than the next-closest team (San Antonio Spurs) and 20.1(!) fewer than the club with the most tries (Utah Jazz).

The results? An offense that ranks fourth in efficiency since April 12 at 115.4 points per 100 possessions after ranking 23rd at 106.7 through games played on April 11.

The backcourt tandem of Westbrook and Beal, the league's No. 2 scoring duo with 3,068 points – 29 behind the New Orleans Pelicans' Zion Williamson and Brandon Ingram – have been the driving force of Washington's recent surge, which should obviously come as no surprise.

Prior to April 12, the Wizards averaged 99.8 points per 100 possessions when neither Westbrook nor Beal were on the court, and 109.9 points when they were playing together. Since April 12, Washington's efficiency without Westbrook and Beal dipped a smidge – 98.9 points per 100 possessions – while its production with both of them on the court has jumped significantly – 117.9 points per 100 possessions.

The offense is running smoother in part because Westbrook is taking smarter shots.

For all the great things the nine-time All-Star and 2016-17 MVP does on the court, shooting three-pointers isn't one of them. Of the 125 players with at least 225 3-point attempts, Westbrook's 31.2 per cent shooting ranks 121st.

Attempting fewer shots from beyond the perimeter would seem to behove Westbrook and the Wizards, and he's complying. After averaging 4.3 three-point attempts in his first 45 games, he's attempting an average of 2.8 three-pointers in the previous 14.

He's done some of his most damage recently from the elbow, where he's shooting 47.9 per cent and has made 35 field goals – second only to Ingram's 41 since April 12.

He made six shots from the elbow in Wednesday's 135-134 road loss to the Milwaukee Bucks, when he finished with 29 points, 17 assists and 12 rebounds for his 19th triple-double in his past 23 games. With 179 triple-doubles in his career, he is now within two of Oscar Robertson's all-time record.

Beal has also cut down a bit on his three-point tries in the past 14 games – 6.4 to 5.5 – but the biggest change to his game in the last three and a half weeks has been he's driving even more to the basket.

Since April 12, his 10.0 field goal attempts on dunks and layups trails only Williamson's 15.1 per game for the league lead. The six-foot-three Beal is making 6.0 of these attempts after making 4.3 and attempting an average of 7.0 dunk and layups through April 11.

While Westbrook and Beal are considered two of the league's top guards, Robin Lopez's name usually isn't mentioned when discussing the NBA's top big men. Heck, he isn't even considered to be the best seven-footer in his own family, but he's been automatic from close range recently.

Among the 173 players with at least 30 shots from within five feet of the basket since April 12, Lopez's 78.4 per cent shooting (29 of 37) ranks sixth in the league. Prior to this stretch, Lopez was shooting 66.5 per cent on all shots within five feet of the hoop – just a tick behind brother Brook at 67.5 per cent.

Lopez isn't the only big man that has stepped up off the bench recently for Washington.

The three-team trade that sent Daniel Gafford from the Chicago Bulls to the Wizards didn't really move the needle on the day of the trade deadline, but it's one that has helped Washington turn their season around.

Of the 199 players with at least 75 field goal attempts since April 12, Gafford ranks fourth in the NBA in eFG per cent at 69.2, just behind Brooklyn Nets superstar Kevin Durant, whose third on the list at 69.7 per cent.

Gafford has also become one of Westbrook's favourite targets, as Westbrook has fed him on 31 made baskets since April 12. That's the most by any guard to a centre and third by any player to a team-mate behind Westbrook to Beal at 39 and the Warriors' Draymond Green to Stephen Curry at 46.

The recent surge in the standings has Washington on the verge of making the playoffs for the first time since 2018, as they sit in 10th place in the East, one-half game back of the ninth-place Indiana Pacers and a comfortable three games ahead of the Toronto Raptors.

Not only are the playoffs within their grasp, with the way Westbrook, Beal and company are playing, the high-octane Wizards have a look of a team nobody would like to face in the postseason.
