Many signs point to Nate joining the tOSU staff after college. That would be 2021. I'd imagine both Nate and Coach M would want a 5-year mentoring period. That puts it out to 2026. So... I think 2030 is a reasonable guess. Retirement at 65. Doubt he'll hang around like Paterno or Bowden.
Can't see him going anywhere else. Notre Dame handed him the keys to their program in 2004... Meyer declined.
16 more seasons. 10 more Natty's. Just sayin'.
Your best guess?
