The San Francisco 49ers pass rush is a major question mark heading into the 2018 season. The team extended Cassius Marsh before he hit free agency, and added Jeremiah Attaochu after free agency began, but otherwise did not invest in the pass rush.
However, they will be counting on some returning players and betting on keeping those players healthy to improve the pass rush. DeForest Buckner has developed into a stud who is hoping to find that next step that results in more sacks. Solomon Thomas had some positive moments in his rookie campaign, but will be looking to find more consistency.
