The 49ers come into the 2021 league year with four defensive backs looking to test free agency: Cornerbacks Richard Sherman, Jason Verrett, K’Waun Williams, and safety Jaquiski Tartt. With that in mind, it was important to have as much continuity as possible, which is why the Monday news that San Francisco re-signed restricted free agent Emmanuel Sanders to a new two-year, $10.1 million contract.
An undrafted free agent out of Tennessee, Mosely became prominent for the 49ers late in the 2019 season, when he replaced Ahkello Witherspoon opposite Richard Sherman as an outside cornerback, replacing Ahkello Witherspoon, who had been getting roasted in coverage. Moseley allowed four touchdowns to one interception in 2020, but that was with injuries all around him, and he’s a decent starting-lever player at his position.
