A big contingent of 49ers coaches, including head coach Kyle Shanahan, were on hand to watch former Stanford players Solomon Thomas and Christian McCaffrey go through a pre-draft workout on Thursday.
Thomas, a defensive lineman who could be drafted higher than any defensive player in Stanford history, went through a series of agility drills along with fellow defensive lineman Jordan Watkins.
A number of NFL defensive coaches, including Bears defensive coordinator Vic Fangio and 49ers defensive line coach Jeff Zgonina watched Thomas' workout. The 49ers have the second overall pick in the upcoming draft; the Bears draft third.
