3. Jerick McKinnon
The third running back spot is not locked up, but it belongs to McKinnon if he’s healthy. The 49ers brought him in prior to the 2018 campaign to be the focal point of their offense. Two knee injuries kept him out of action during his first two years in Santa Clara. Now he’s cleared for action and gets some additional time off while the NFL figures out how to proceed amid COVID-19 shutdowns. If McKinnon is healthy, he’ll have a role as a dual-threat back for the 49ers.
