Ryan Day looked into his NFL past to find Jeff Hafley.
Both Day and Hafley, whom Day hired on Monday as Ohio State's co-defensive coordinator, worked under Chip Kelly with the San Francisco 49ers in 2016, though they coached on different sides of the ball. Day coached quarterbacks, while Hafley led the defensive backs.
