The surging Denver Nuggets (44-19) host the struggling Memphis Grizzlies (38-23) on Friday in a clash between the top two teams in the Western Conference.

Since the turn of the year, only the 22-5 Milwaukee Bucks have boasted a better record than Denver's 21-7, and the Nuggets have surged to a five-game lead atop the West.

Their closest challengers are the Grizzlies, who have been flailing since starting center Steven Adams suffered a knee injury on January 22, going 7-8 in the 15 games since.

Adams is only averaging 8.6 points per game in his 27 minutes of action, while shooting a league-worst 36.4 per cent from the free-throw line, but his impact on the Grizzlies' success has proven to be immense.

During the first 46 games of the season – prior to Adams' injury – the Grizzlies owned the best defensive rating in the NBA, while also boasting the second-best rebounding rate, and a top-10 offense.

Since then, Memphis have held up surprisingly well defensively and have been fourth in defense over the past 15 games, but their offense has cratered – becoming the 24th-ranked unit – and their ability to rebound has fallen off a cliff.

Adams leads the team at 11.5 rebounds per game, but his value goes far beyond just the rebounds he hauls down himself, as he is almost universally considered the physically strongest player in the league, and he uses that to wreak havoc on the offensive boards.

The Grizzlies have been 27th in rebounding rate since his injury, falling from the second-best offensive rebounding team to 18th in that category, while also dropping from 15th in defensive rebounding to 28th.

While it is easy to point to some recent cold shooting from Memphis as the reason for their recent struggles – 29th in three-point percentage (31.7 per cent) since Adams' injury – it is their failure in the rebounding department that is ruining a lot of their good work.

It is great to have a top-five defense, but when you are only gathering 68.2 per cent of opponents' misses, it means that even your strength is no longer a strength.

It goes to show that while Jaren Jackson Jr is Memphis' best defensive player – and a strong favourite to win Defensive Player of the Year – Adams may be their most important piece on that end. 

That is even more true when the other team rolls out a center like Nikola Jokic.

Jokic, the reigning back-to-back league MVP and favourite to earn the first three-peat since Larry Bird from 1984-86, is essentially unguardable, but it is incredibly helpful to have a physical presence like Adams who is impossible to push around and can at least dictate Jokic's catch positions.

With Adams out, Jackson will likely assume the responsibility, and while that is a mouth-watering matchup between arguably the league's most gifted players on each side of the ball, the Grizzlies ace will need to be on his most disciplined behaviour.

Leading the league with 3.3 blocks per game, Jackson also sits sixth in fouls per game (3.4), and could leave his team without an anchor on the defensive end if the crafty Jokic draws a couple of early calls and puts his opponent in foul trouble.

But Jokic, while almost flawless on the offensive end, still has his own exploitable warts defensively.

The Serbian has shed the reputation of being a poor defender – leading all centers with 1.3 steals per game – but remains a liability when it comes to protecting the rim, with Denver ranking 25th when it comes to preventing points in the paint.

That is where the Grizzlies will see their greatest advantage as the league leaders for points in the paint, with Ja Morant's 14.8 points per game in that area trailing only Oklahoma City Thunder star Shai Gilgeous-Alexander (15.5) for the most among all guards.

Denver's plan of attack will likely be the complete opposite, as Memphis are the fourth-best team at preventing points in the paint but allow the fourth-most made three-pointers per game, while the Nuggets lead the league in three-point percentage (39.2 percent).

PIVOTAL PERFORMERS

Memphis Grizzlies – Ja Morant

Sometimes it is complicated to see whose impact will have the greatest effect on their team's success, and sometimes it is painfully obvious.

Morant is the Grizzlies' franchise player, leading scorer (27.1 points per game), leader in assists (8.2) and the heartbeat of their fast-paced, rim-attacking offense.

It will be his responsibility to exploit Jokic's defensive deficiency and generate high-quality looks inside for himself and team-mates, as Memphis are likely doomed if they have to rely on outside shooting (24th in three-point percentage).

Denver Nuggets – Jamal Murray

The Nuggets know what they are going to get from the metronomically consistent Jokic on a nightly basis, but the contributions from second star Jamal Murray are often what make or break their results.

In the 35 wins he has played in this season, Murray is averaging 21.7 points and 6.1 assists per game while shooting 48.3 per cent from the field, 41.6 per cent from deep and 85.5 per cent from the free-throw line.

In 14 losses, those figures plummet to 16.3 points and 5.5 assists on dismal shooting splits of 38.2/29.7/76.9 – illustrating that when it is not Murray's night, it is usually not the Nuggets' night either.

KEY BATTLE – Can Denver capitalise on the absence of Adams?

While Jokic is one of the best defensive rebounders in the league, having the third-best rate among players averaging at least 20 minutes, he is not even close to the same kind of threat on the offensive boards, where Adams' absence will be felt.

If Memphis can figure out how to limit Denver to one shot per possession and secure the defensive glass, it will not just limit second opportunities, but it will ignite the Grizzlies' fast-break offense and allow Morant to operate in the open floor with a runway.

Another key factor is that while Denver have been shooting the lights out, and Memphis have been struggling from distance, three-point percentage is often a stat that regresses to the mean over time, meaning at some point their fortunes will likely reverse.

HEAD-TO-HEAD

These sides have split their two meetings this season, with Denver securing a 14-point home win in December, before Memphis evened the ledger with an 18-point home win of their own in January.

It fits with their evenly matched recent history, with a 2-2 record from their past four meetings, and a 5-5 record dating back to January 2020.

Center Steven Adams has signed a multi-year extension with the Memphis Grizzlies.

Though terms were not officially disclosed when the agreement was announced on Saturday, a report from Adrian Wojnarowski of ESPN stated it to be a two-year, $25.2million deal.

The 29-year-old New Zealander has altered his role in recent years, having previously averaged 13.9 points per game in consecutive seasons for the Oklahoma City Thunder between 2017 and 2019.

Last season, he averaged just 6.9 points for the Grizzlies, but had his best campaign ever for both rebounds (10.0 per game) and assists (3.4 per game).

In fact, his 349 total offensive rebounds and 4.6 offensive rebounds per game were the best numbers in the league, breaking the single-season franchise records set by Zach Randolph during the 2009-10 season.

The Grizzlies begin the 2022-23 season at home to the New York Knicks on October 19.

As one of only two NBA teams that have never won a division title, the Memphis Grizzlies are in prime position to cut that number in half this season.

Since joining the NBA as the Vancouver Grizzlies in 1995-96, Memphis have finished second five times but have never captured a division crown. The Charlotte Hornets are the only other franchise never to win a division title, though they did finish in a three-way tie for first place in the Southeast in 2015-16 but lost the title to the Miami Heat on a tie-breaker.

Roughly two months into this season and Memphis sit atop a weak Southwest Division with the franchise's first division title a distinct possibility.

No division has a worse composite record than the Southwest with Memphis (17-11), the Dallas Mavericks (14-13), San Antonio Spurs (10-16), Houston Rockets (9-18) and New Orleans Pelicans (8-21) combining for a 58-79 record (42.3). Weaker division opponents certainly will not hurt the Grizzlies' cause, but they appear more than capable of beating just about any team, evidenced by their 13-6 record against the Western Conference.

While Ja Morant has established himself as one of the game's young superstars in his third season, what is most impressive about the Grizzlies is how they have performed without him.

Morant has not played since November 26 due to a sprained left knee and he then entered the NBA's health and safety protocols after testing positive for COVID-19 on December 8.

Somehow, Memphis have been even better with their leading scorer on the shelf, going an inspired 8-1. Prior to this stretch, Memphis were 6-9 in Morant's career when he missed a game.

It has been a dominant run for the Grizzlies, who have outscored opponents by 176 points in those nine games. Since November 28 in their first game without Morant, the Grizzlies rank fifth in the NBA in points per game (113.7), ninth in three-pointers made (112) and lead the league in total rebounds (449) and total steals (108).

Clearly, Memphis are much more than just Morant.

During a five-game winning streak – all without Morant – the Grizzlies led every game from wire-to-wire before the run ended with a 104-96 loss to visiting Dallas on December 8. Included in that five-game surge was a stunning 152-79 thrashing of the Oklahoma City Thunder for the largest margin of victory in league history.

Memphis only rank 20th this season in opponent points per game (109.2) but something has clicked with the defence allowing a league-best 94.1 points during this 8-1 stretch. In the first 19 games this season, Memphis held foes to 101 points or fewer just twice but have done that seven times in the past nine contests.

Memphis are 13-1 (92.9) this season when holding opponents under 110 points. Only the Phoenix Suns (18-0), Charlotte (7-0) and Brooklyn Nets (15-1) have a better winning percentage in such games.

Maybe it was Morant's absence that forced the rest of the team to turn up the defensive pressure, but whatever the reason Taylor Jenkins' team now know they can win either with offense as they rank sixth in the league in scoring (111.0) as well as at the opposite end of the court.

Perhaps no victory was more indicative of what the Grizzlies can do than last Thursday's 108-95 win over the Los Angeles Lakers. Despite missing Morant and starting guard Dillon Brooks (health and safety protocols), Memphis set a franchise record with nine steals in the second quarter en route to a season-high 18 and became just the second team in the past 13 games to hold star-laden Los Angeles under 100 points.

Several players have stepped up to fill the void left by Morant and none bigger than second-year guard Desmond Bane. A serious contender for the Most Improved Player award, Bane has taken a huge step forward in his sophomore season to become much more than a shooter with his usage rate going from 16.1 to 22.3 per cent.

In the nine games without Morant, Bane has averaged 17.1 points, 5.6 rebounds and shot 44.8 per cent from three-point range (26 for 58). He averaged 15.5 points and 3.8 rebounds while connecting on 37.4 per cent (46 for 123) from deep in the season's first 19 games. His points per game average has risen from 9.2 in 2020-21 to 16.0 this season – his plus-6.8 improvement only bettered by Reggie Jackson (+6.9), Miles Bridges (+7.1) and Tyrese Maxey (+8.7) among players to have played in 70 per cent of team games in both campaigns.

When a team's leading scorer misses time, the second-leading scorer is asked to pick up most of the slack and Jaren Jackson Jr. has answered that call.

During the 8-1 stretch, Jackson is scoring 21.1 per game on 50.4 per cent shooting, including 38.5 per cent (20 for 52) from beyond the arc. In 19 games played with Morant this term, Jackson averaged 14.8 points on 39.7 per cent from the field and 33.7 per cent from long range.

Jackson has scored 25 points or more in four of his last seven games after having only one such game through his first 20 this season.

With 25 points and five blocks in a win over the Toronto Raptors late last month, Jackson became just the third Grizzlies player to reach both those totals in a game since the team moved to Memphis. Pau Gasol (six games) and Marc Gasol (four games) are the only others.

Memphis' defensive improvement is clearly a team-wide concept, but Dillon Brooks may be the player most responsible. Brooks did not make his season debut until November 10 due to a broken left hand and the team clearly missed his intensity and leadership.

In 14 games this season with Brooks in the line-up, Memphis have surrendered 103.6 points per game and held opponents to 44.0 per cent shooting. In the 14 games he has missed, the Grizzlies have given up 114.9 points with opponents making 48.3 per cent of their shots.

Taking over at the point in Morant's place has been Tyus Jones, who had the best assist-to-turnover ratio in the league each of the last three seasons and is on his way to doing it again with 119 assists to 21 turnovers (5.67).

The biggest improvement in Jones' game has been his three-point shooting, making 40 percent of his first 65 attempts after he hit on just 32.1 per cent last season.

One area where Memphis have excelled all season is on the boards.

The Grizzlies rank third in the NBA in total rebounds (1,323) and tied for second in offensive rebounding (358). Steven Adams leads the way with 8.6 per game but gets plenty of help as Memphis are tied for second in the league with seven players averaging at least four boards per contest.

Those rebounds play a role in helping Memphis top the NBA in both second-chance points (479) and points in the paint (1,504).

With Phoenix and the Golden State Warriors looking like world beaters right now and the Utah Jazz not far behind, Memphis have been able to fly under the radar in the Western Conference.

While there is no telling how Morant's return will affect the Grizzlies, the team have done all the little things in his absence and that can only help them in their quest to finally hang a division championship banner at FedEx Forum.

The Memphis Grizzlies are trading up to the 10th pick in Thursday's NBA Draft but must give up Jonas Valanciunas to the New Orleans Pelicans while taking Steven Adams and Eric Bledsoe in return.

ESPN reported the Grizzlies were finalising a deal on Monday that would see them trade selections 17 and 51 for the Pels' 10 and 40 as well as a top-10 protected 2022 pick via the Los Angeles Lakers.

Lithuanian center Valanciunas leaves Memphis after two and a half years, having been the team's third scorer in 2020-21 with 17.1 points per game behind Ja Morant (19.1) and Dillon Brooks (17.2).

He also averaged 12.5 rebounds but heads to New Orleans, where he will be expected to create space for Zion Williamson.

It means another offseason of flux for the Pels, who selected Williamson with the first overall pick in 2019 as former number one selection Anthony Davis left for the Lakers.

The team have so far struggled to surround Williamson with the right talent, although he was an All-Star last season with 27.0 points – the eighth-most in the league.

Adams and Bledsoe arrived in 2020 as another star performer departed, this time Jrue Holiday in a four-team trade. Holiday won the title last week with the Milwaukee Bucks.

Adams contributed only 7.6 points per game and struggled to work in tandem with Williamson, while Bledsoe's 12.2 points made for his worst scoring season since 2012-13.

Crucially, the pair were set to count for more than 21 per cent of the Pels' cap in 2021-22.

New Orleans now have the flexibility to make an offer to Lonzo Ball or to eye up other free agents, including linked Toronto Raptors great Kyle Lowry.

The Grizzlies instead take on Adams' $17.1million and Bledsoe's $18.1m, but they do also now get a look at a top-10 pick in a talented draft class.
