One down, plenty more to go. While the opening round of the NBA playoffs has already produced plenty of drama, the Miami Heat's hopes of a repeat run have been extinguished.

The 2020 finalists fell at the first hurdle this time around, swept aside by a Milwaukee Bucks team now waiting to find out who they will face next. As for the defending champions, the Los Angeles Lakers are finding the going tough against the Phoenix Suns, that series one of three in the Western Conference delicately balanced at 2-2 through four games.

In the East, the picture looks somewhat clearer. Still, as the Denver Nuggets demonstrated last year in the NBA's Florida bubble, no 3-1 series lead is safe in the playoffs.

As the contests keep coming thick and fast, Stats Perform takes a brief pause to review those stepping up in the the playoffs, as well as the players who could do with finding some form again.

RUNNING HOT

Ja Morant

Having helped the Memphis Grizzlies come through the play-in tournament, Morant has continued to dazzle in the series against the Utah Jazz. After 26 points in the opener, the second-year point guard has dropped 47 and 28 in the next two meetings, albeit on neither occasion were his efforts enough to secure his team a victory.

Still, he is averaging 33.7 points per game against Utah, a huge upturn from 19.1 in the regular season. So, just how good has he been? Well, in reaching a century of points through his first three playoff games in the NBA, Morant matched a feat previously only achieved by Kareem Abdul-Jabbar, Wilt Chamberlain and George Mikan.

Derrick Rose

Rose has claimed the starting point guard spot from Elfrid Payton for the New York Knicks as they go up against the Atlanta Hawks, a series the latter now leads 3-1 after a 113-96 triumph on Saturday.

Elevated off the bench, Rose has managed a combined total of 48 points in back-to-back losses on the road, during which he landed five of his nine attempts from deep. Payton, meanwhile, has scored one point in just 13 minutes of court time during the playoffs and did not get off the bench at all the past two games after averaging 10.1 points per game in the regular season.

Kawhi Leonard

"This is playoff basketball, we've just got to figure it out." Those were Leonard's words as the Los Angeles Clippers faced a 2-0 deficit as they headed to Dallas to continue their battle with the Mavericks.

It is safe to say the two-time NBA Finals MVP has done just that on his travels, helping his team fight back to level the series between the fourth and fifth seeds in the West. Across the past week, Leonard has averaged 35.7 points, aided by sinking 21 of his 23 attempts from the free-throw line, as well as contributing 24 rebounds. Playoff Kawhi means business this year.

GOING COLD

Shake Milton

Having averaged 13.0 points per outing in the regular season, Milton has endured a playoff slump for the Philadelphia 76ers as his minutes have been reduced. So far, the 24-year-old has managed nine points in a series that has seen his team hold control throughout.

Milton has managed to land only two of his 12 shot attempts, including missing all six in Game 2. In the following outing, head coach Doc Rivers opted to use Tyrese Maxey ahead of his team-mate off the bench, a move that may become a regular feature as the 76ers look set to move on to round two.

Enes Kanter

For the Portland Trail Blazers in the regular season, Kanter averaged 11.2 points and 11.0 rebounds per game. In the playoffs, however, it has been a different story for the veteran center.

After playing over 32 minutes across the first two games against the Denver Nuggets, Kanter has now figured in a little over nine in the following two. During his limited opportunities, there have been no points, two rebounds and a solitary blocked shot. Up against Nikola Jokic, the Blazers have opted to go with alternative options when starting center Jusuf Nurkic is taking a seat on the bench.

Montrezl Harrell

Make no mistake, the Lakers are locked in a battle with the Suns. Phoenix were impressive in taking Game 4 on the road on Saturday to draw level, during which the 2019-20 Sixth Man of the Year was finally called into action again by head coach Frank Vogel.

However, Harrell's appearance was fleeting. Having averaged 13.5 points during the regular season when playing just under 23 minutes per outing, he has been a non-factor in the playoffs. After not even making it onto the court in the previous two games, his brief cameo at the weekend saw him fail to muster a shot as LA lost at home. Across the past week, he has not scored a single point.
