The 49ers drafted Solomon Thomas in the first round this year, making it three straight years that the team has used a first-round pick on a defensive linemen. Those two players — Arik Armstead and DeForest Buckner — join Thomas, Earl Mitchell, Aaron Lynch, Tank Carradine, Elvis Dumervil, Quinton Dial and 2017 sixth-round pick D.J. Jones up front for the Niners.
