Ohio State is expected to use its 10th assistant position on bringing in one of the top defensive coaches in the country. According to multiple reports -- including ESPN's Chris Low -- Alex Grinch has agreed to join Urban Meyer's staff as co-defensive coordinator.

Grinch has been the defensive coordinator at Washington State for the last three seasons, improving a group that had previously ranked near the bottom of the Pac-12 prior to his arrival in Pullman. This past season, the Cougars ranked No. 4 nationally in third-down defense and finished second in the Pac-12 in total defense.

Prior to Washington State, Grinch, 37, was the safeties coach at Missouri.
