4. Jaren Jackson Jr., Memphis Grizzlies

Jaren Jackson Jr. is another big man who looks ready to make an impact at the next level. The future Memphis Grizzlies big man put up 28 points on 8-of-13 shooting from 3-point range back on July 2 in Utah Summer League against the Atlanta Hawks. Through three games in Utah, he put up 15.7 points, 5.0 rebounds and 2.3 blocks per contest.

To open his Vegas action, JJJ poured in 12 points, eight rebounds and four blocks against the Detroit Pistons. His skill-set was on full display all summer, giving a lot of fans a glimpse of what he’s capable of.

In Las Vegas, he averaged 11.2 points, 8.2 rebounds, 3.8 blocks and 1.2 steals through five games. He shot just 41 percent (17-of-42) from the field, but he didn’t look hesitant at all adjusting to the speed of the NBA and earned a Second Team All-Summer League selection.

It’s hard to call Jackson a Day 1 starter, but he certainly has the tools to earn the job before the 2018-19 season begins. He’ll be looked upon to do a lot for the Grizzlies’ franchise, but if he focuses on being a defensive stopper in the early going, he should have a solid rookie season.
