Defensive Line (8)
Weak-side Defensive End: Arik Armstead, Dee Ford
Weak-side Defensive Tackle: DeForest Buckner, Kentavius Street
Strong-side Defensive Tackle: D.J. Jones, Solomon Thomas
Strong-side Defensive End: Nick Bosa, Ronald Blair
Starters are listed for base, run-stopping formations. Ford, who isn’t much of a run stopper, will come in and play the weak-side edge-rushing spot on passing downs. Nose tackle D.J. Jones will be off the field, opening up a rotation between Armstead and third-year pro Solomon Thomas, who is looking much more rejuvenated in training camp so far. That’s a good thing.
The 49ers’ top pick from this year’s NFL Draft, EDGE Nick Bosa, has also impressed a lot during training camp. Not just a top-tier pass-rushing prospect, Bosa held his own against the run at Ohio State, too. He could easily wind up being an every-down player.
Even though Robert Saleh stressed to remind reporters Bosa is still just a rookie.
Either way, the Niners boast five former first-round draft picks along their defensive line, including 2018 Pro Bowler DeForest Buckner, whose prowess should only improve with the added talent.
San Francisco’s defensive line is easily the deepest position on the team during training camp, and it could arguably wind up being a top-five unit in this category for 2019, too.
