The 49ers are transitioning to a zone offense. This means they need a slight overhaul of their offensive line. While they’re pretty well set at tackle (at least until Joe Staley departs), the interior of their line needs some work. Jessamen Dunker is certainly athletic enough to handle himself in a zone offense, running the second best 40 yard dash at the NFL combine. He has excellent size as well, standing at 6-foot-4 and 318 pounds. Dunker needs time to develop, but the 49ers can offer him that. He could emerge as a starter in 2018 or 2019 for them.
Few teams have shallower defensive line depth than the San Francisco 49ers. This rings especially true at defensive tackle. Switching to a 4-3 scheme, they need to add someone during the draft. Ryan Glasgow should emerge as a solid starter. His run stopping is the best part of his game. While Glasgow likely won’t be much of a pass rusher, he should be a very solid two down player. He shouldn’t be a day one starter, but looking at the 49ers depth, he might need to be one, especially if Earl Mitchell or DeForest Buckner suffer an injury.
