Running backs Justice Hill and Keaton Mitchell: There’s not a lot that running backs can do to stand out in OTA and minicamp practices besides catch the ball and run fast. Hill and Mitchell, a well-regarded undrafted rookie, did just that. With J.K. Dobbins and Gus Edwards not participating in team drills, Hill showed his vision and cutback ability a few times on zone runs behind the first-team offensive line. Mitchell, a productive receiver at East Carolina, was comfortable catching passes out of the backfield and didn’t need long to reach top speed. He could push for a spot on the 53-man roster.
