The 49ers hope that first-round pick Solomon Thomas can be a disruptive presence on their defensive line and he spent time Thursday working out with and talking to players who can offer him some good advice about how to meet that goal. Broncos linebacker Von Miller organized a “pass rush summit” at Thomas’ alma mater Stanford on Thursday and the guest list was a pretty strong one. Miller was joined by his successor as defensive player of the year Khalil Mack, 2016 NFL sacks leader Vic Beasley, Seahawks defensive end Cliff Avril and the recently retired DeMarcus Ware.
