In 2019, once fully recovered from an Achilles injury, Sherman had one of the best seasons of his entire career, allowing just 227 receiving yards all season long. He surrendered a passer rating of just 46.8 before things came unglued a little in the Super Bowl loss to Kansas City. In 2020, Sherman produced a 67.2 coverage grade on just 332 snaps, the lowest grade of his career.
Sherman’s intelligence and tape study gives him a mental edge over most offenses he faces, and that more than makes up for less than stellar straight-line speed. In the kind of defense he plays in San Francisco, he can remain a valuable player even at his age and could be an attractive short-term option for a number of teams in need of a quick fix.
