Utah’s acquisition of the former Kia Defensive Player of the Year was one of the big moves of last week’s NBA trade deadline. In the swap, Utah acquired Jackson, Jock Landale, John Konchar and Vince Williams Jr. from Memphis for Walter Clayton Jr., Kyle Anderson, Taylor Hendricks, Georges Niang and three future first-round picks.

In three games with the Jazz, Jackson posted 22.3 points, 4.3 rebounds, 2.7 assists and two blocks per game while shooting 49% overall and 33.3% on 3-pointers. This season, he is averaging 19.4 ppg, 5.7 rpg, 2 apg and 1.4 spg while shooting 47.6% overall and 35.7% on 3-pointers.

Jackson spent his entire eight-season career with the Grizzlies after they selected him No. 4 overall in the 2018 Draft. He and Ja Morant comprised the core of Memphis’ team as it rose from a lottery team to a Play-In Tournament team to a playoff team in short order.

The Jazz added Jackson, who is under contract through the 2029-30 season (he has a player option) to a core that includes All-Star Lauri Markkanen, guard Keyonte George, young swingman Ace Bailey, injured center Walker Kessler and a host of other talent.

Konchar is under contract through next season, while Williams has a team option for 2026-27. Landale, who will be a free agent this summer, was moved to the Atlanta Hawks in a separate trade after he was acquired.
