In this impressive rookie class, we saw some strong performances change up the Rookie Fantasy Power Rankings dramatically. A sample size is starting to form with us now in Week 4 of the NBA fantasy season. There continue to be four impressive rookies battling it out for the top spot. After a big week, there is another change at No. 1, along with a guard entering our rankings and climbing quickly.

10. Aday Mara – Oklahoma City Thunder

Last Week: 9↓

The Thunder clearly value Mara as a backup center, and he’s already started in two of his first 10 career games. Saturday’s victory over the Wizards saw the 12th overall pick put up a career-high 18 points to go along with 8 rebounds, 3 assists and 3 blocks. Even with so many injuries to its rotation, Oklahoma City remains 8-2. Mara is a big reason why this team ranks second in defensive rating right now, averaging 8.1 points, 5.9 rebounds and 1.9 blocks (first among rookies). The former Michigan big man has a higher fantasy floor than most first-year players.

9. Keaton Wagler – LA Clippers

Last Week: 7↓

Wagler had one of his more productive weeks in Week 3, but the minutes just aren’t there right now to move up higher on this list. In two games over the last week, Wagler averaged just 17 minutes. He averaged 13 points, two rebounds and 2.5 assists in that span. We expect the Clippers to give their top-five pick more runway to take off later in the season, but for now this is around his ceiling on our Rookie Fantasy Power Rankings.

8. Meleek Thomas – Cleveland Cavaliers

Last Week: 8

Thomas is starting to be valued as a legitimate sixth man in Cleveland’s rotation. More fantasy users have picked him up since his 16-point debut on Oct. 26, and they’ve been rewarded, as he’s averaging 13 points, 2.6 rebounds and 1.1 steals on 47% shooting and an absurd 47.8% from 3-point range (5.8 attempts). Of the rookies averaging at least two attempts from beyond the arc, Thomas leads the pack. He’s proving to be a great pickup in deeper leagues.

7. Brayden Burries – Milwaukee Bucks

Last Week: NR↑

The Bucks made a significant change in their starting lineup last week, opting to start the rookie Burries over Ryan Rollins. Burries has started the last four games for the Bucks, averaging 28.6 minutes. In that span, he has been productive, averaging 13 points, 8.3 rebounds and 3.5 assists. With the Bucks 1-9 on the season, there is no reason for them to shy away from Burries, or any of their other young players. That will give this Arizona Wildcat plenty of runway to improve as the season goes on. His 3-point shot has been his weakness so far, but with more reps expected, Burries can become a very useful fantasy asset in the second half of the season.

6. Darryn Peterson – Utah Jazz

Last Week: 6

Peterson’s last two games have been on par with the top rookies in the NBA right now. He notched 21 points, 5 assists and 2 steals on Nov. 6, then followed that with 26 points, 6 rebounds and 4 assists on Sunday. The efficiency is starting to improve, but even in High Score leagues, the second overall selection is a great pickup if he can have these outbursts once or twice a week. The Jazz are 1-9 to start the season, so they may turn to Peterson more if the offense stalls. Utah is currently 29th in offensive rating.

5. AJ Dybantsa – Washington Wizards

Last Week: 5

Dybantsa continues to look great as he gets more NBA reps. The No. 1 overall pick averaged 15 points, 7.3 rebounds and 2.5 assists in the four games he played over the last seven days. The efficiency wasn’t there, as he shot just 38.6%, but it’s encouraging to see him still shooting. On a team with Trae Young and Anthony Davis, Dybantsa averaged 14.3 field-goal attempts even while struggling. This continues to be around his floor in our Rookie Fantasy Power Rankings.

4. Cameron Boozer – Memphis Grizzlies

Last Week: 3↓

Boozer is still a near-double-double machine, averaging 16.2 points, 9.7 rebounds and 5.5 assists as an all-around contributor. He’s still third among rookies in High Score points (39.9), so while his scoring might be slightly inconsistent, he is almost guaranteed to make up for it on the glass and as a facilitator. That’s huge for fantasy users. Monday saw the third overall pick put up one of the best games of his early career with 22 points, 7 rebounds and 8 assists to push Memphis to 7-3.

3. Caleb Wilson – Chicago Bulls

Last Week: 2↓

Caleb Wilson had his first down week of the season, as he struggled with his shot. The fourth overall pick averaged 11.5 points and five rebounds on 30% shooting in his two contests over the last week. Even in this loaded rookie class, young players are going to occasionally struggle in short sample sizes and that is what happened with Wilson this week. It’s enough to knock him down a spot in our rankings from last week, but no reason to be concerned going forward.

2. Yaxel Lendeborg – Golden State Warriors

Last Week: 1↓

Don’t let Lendeborg’s dropping one spot deter you from what he’s continuing to do. The Warriors have won eight straight games since starting 0-3, and he has been a driving force in that. The 6-foot-9 forward is averaging an extremely efficient 21.4 points, 7.2 rebounds and four assists on 52.3% shooting and 44.3% from 3-point range. Lendeborg ranks top four among rookies in points, rebounds, assists and fantasy points. He is the clear second option in Golden State after Stephen Curry.

1. Darius Acuff Jr. – Sacramento Kings

Last Week: 4↑

We have a new No. 1. The Arkansas product continues to fire up shots at a historic pace for a rookie. The difference over the last seven days compared to the start of the season is that more of those shots went into the hoop. Over the last week, Acuff is averaging 25.3 points, 3.7 rebounds and a whopping 10 assists. He did that on a respectable 43.1% shooting on 21.7 field-goal attempts. Unlike other rookie guards on this list, the Kings have unlocked the handcuffs here from day one. This week he averaged 38 minutes. This has been Acuff’s team from the very beginning and he could become a fantasy MVP if he continues to improve his efficiency.
