DT DJ Jones
Losing Jones for the season to a high ankle sprain in Week 14 was a significant blow to the 49ers’ defense in 2019. He was starting to emerge as a force in the interior of their defensive line, and DeForest Buckner’s departure this offseason only opens the door for Jones to see an even larger role this year. He’s a consistently strong run defender who flashed some pass rush ability last year with a pair of impressive sacks. He could wind up being a sizable factor in replacing Buckner if he generates pressure more consistently.
