Defensive Line

Nose Tackle: free agent

Defensive Ends: DeForest Buckner, Arik Armstead

Again, assuming the Niners stick in a 3-4 alignment, there is only some minor tweaking needing to be made here.

Defensive ends DeForest Buckner and Arik Armstead are cornerstone pieces. They won’t be going anywhere, even if Armstead had a down year in 2016. Remember, his shoulder injury — which eventually ended his season — ultimately played into his lowly stats and efforts.

The key question is what to do at the nose.

Defensive tackle Quinton Dial is better suited as an end, and he’s not going anywhere — signed through 2019. But look for him to be a backup and rotational player instead of a starter.

Fortunately, nose tackles tend to be fairly cheap on the open market. At least for a decent one. Maybe San Francisco brings back former Niners NT Ian Williams. But Williams’ injury concerns make this a pressing need still. So it wouldn’t be surprising to see San Francisco dip into free agency.
