Former 49ers defensive backs coach Jeff Hafley will leave the team to join Ohio State as their co-defensive coordinator, according to Yahoo! Sports.
Hafley will work under Ohio State head coach Ryan Day, who was the 49ers quarterbacks coach in 2016. Day and Hafley both worked for the 49ers that season. They know each other.
Hafley was one of the worst position coaches on the team. During his three seasons with the 49ers, none of their young defensive backs ever improved. The 49ers are better off without Hafley.
