NBA Rookie Rankings: What’s Luka Doncic’s biggest weakness?
3. Jaren Jackson Jr.: Foul rate
When Jackson is able to stay on the floor for long stretches of time, the Grizzlies look like a fringe playoff contender in the West. When he gets stuck on the bench due to foul trouble, they look like a team in contention for the No. 1 pick in next year’s draft.
It’s rare to see a rookie contribute so much to his team’s fortunes, but Jackson has been that good when he’s been in the game. He’s averaging 13.4 points per contest on a true shooting percentage that remains over 60. He needs to improve his rebound rate at both ends of the floor, but he’s exceeded even optimistic expectations in Memphis.
The trouble is that Jackson is only averaging 25.4 minutes per game. Some of that is due to JB Bickerstaff’s inexplicable rotations, but a lot of it can be attributed to Jackson’s propensity to pick up fouls at an alarming rate. Averaging 5.5 fouls per 36 minutes is a good way to make sure you’re on the bench for long periods of time.
The good news is that nothing about Jackson’s physical gifts require him to be so foul prone. His necessary adjustment is mental. Occasionally, Jackson might have to give up a drive when he’s caught out of position. Reaching in to try to cover up his error usually leads to a blown whistle.
Jackson’s big problem is infinitely fixable, but he needs to start showing signs of progression as the season goes along. If he doesn’t, it may be an issue that plagues him throughout the prime of his career. There’s a real danger that he’ll become a marked man for NBA officials.
