Despite Urban Meyer's retirement, Ryan Day and Ohio State are expected to remain most of the staff members who have become critical to day-to-day operation of the team, including Mickey Marotti, Mark Pantoni, Ryan Stamper and Brian Voltolini, according to multiple reports.

From Pete Thamel of Yahoo.com:

Part of Meyer’s legacy at Ohio State will be the prolific machine he’s grown the program into, as Ohio State has emerged as a force nationally in recruiting with top-three rankings in each of the past three seasons. All indications point to Day planning to keep veteran strength coach Mickey Marotti, director of operations Brian Voltolini, respected personnel director Mark Pantoni and player development director Ryan Stamper. Day would certainly have say over staff decisions, but the general notion of keeping the off-field machine Meyer put into place has to be an attractive one.

All four key staff members will be retained, according to both Thamel and Bill Rabinowitz of the Columbus Dispatch.

Marotti is one of, if not the most respected strength and conditioning coach in the country. More than that, Marotti spends more time with the team than anyone else on staff one of the few coaches besides the head coach that has personal relationship with every player. Because of this, he was a key member of the staff during Meyer's suspension.

Pantoni's retention will be especially key as Ohio State tries to maintain its 2019 and 2020 recruiting classes.

Stamper plays a critical role in player development – discipline, helping them transition to college, assisting with academics – while Voltolini worked closely as an assistant to Meyer since his time at Bowling Green.

Keeping those four on staff will be invaluable as Ohio State makes a transition at the top.
