Jaren Jackson Jr. was voted as the most dominant defender in the NBA last season after winning Defensive Player of the Year and being named first-team all-defense. A year later, Jackson’s standing in the NBA has changed.

The Memphis Grizzlies big man was not named to one of the 10 spots on the first and second all-defensive teams on Tuesday afternoon, the NBA announced. He only received one vote for a spot on the second team. Jackson also didn’t receive any votes for Defensive Player of the Year last week.

Jackson was named first-team all-defense in each of the previous two seasons. He was the only NBA player to achieve that honor.

Memphis had a lot of team success in the previous two seasons that helped Jackson’s case. The Grizzlies won more than 50 games in each season and finished as the No. 2 seed in the Western Conference.

Things didn’t go as smooth this season. Injuries led to Memphis setting an NBA record for most players used in one season, and the Grizzlies finished 27-55 — the third-worst record in the west.

Despite the Grizzlies’ lack of team success, there was reason to believe Jackson could earn his third straight all-defensive team appearance. Before the season, the NBA created a new rule where players would need to play in at least 65 games to be eligible for major awards. That removed several worthy candidates and increased Jackson’s chances after he played 66 games.

Memphis finished last in the NBA with a 107.2 offensive rating. Jackson anchored the Grizzlies’ defense that limped to an impressive 12th-best rating in the NBA despite the massive turnover. Jackson’s 66 games played led Memphis this season.

Even though Jackson’s presence was felt, his defensive impact was different than the past two seasons. His blocks went down to 1.6 per game after he had led the NBA in that category each of the past two seasons. Jackson averaged three blocks en route to winning Defensive Player of the Year, and he totaled 2.3 blocks per contest two seasons ago.

Grizzlies coach Taylor Jenkins pointed out Jackson’s different role in the defense as a reason for some of those differences. Jackson played center more this season than any previous year of his career.
