RB Jerick McKinnon
An ACL tear a week before the start of the 2018 season knocked McKinnon out for his first year with the 49ers. Complications in that same knee pushed him out for the 2019 campaign. Offseason workout videos show that McKinnon is healthy and working at full speed. A fully healthy McKinnon was brought in to be a focal point of the 49ers’ offense. A full stable of running backs will probably limit McKinnon’s touches if he’s available in 2020, but his pass-catching prowess could wind up making him the team’s most effective running back.
