Though the staff he inherited from Urban Meyer already features a pair of experienced and respected staff members in offensive coordinator Kevin Wilson and associate head coach/defensive line wizard Larry Johnson, half of Day's assistants have been coaching at the FBS level for less than a decade.
With the hire of veteran defensive coordinator Greg Mattison, though, Day has a seasoned leader taking over a unit in dire need of a revival. The regression of Ohio State's defense under the previous coordinator, Greg Schiano, was well documented. But with 18 seasons as a coordinator under his belt, including three with Urban Meyer at the Universty of Florida and two more with the Baltimore Ravens, Mattison brings a wealth of knowledge that should help Day sleep at night.
