Lemonis was tough to leave off due to his national championship. But its hard to drop one of the other 5 for someone with only 5 seasons at MSU. He can certainly move up if he rights the ship.
Sorry to bump this, but after going down a small Allyn McKeen rabbit hole, I have to replace Lemonis with him.
I know he coached before basically all of us were born, but he's in the College Football HOF (I didn't realize that). Here are his years at State, with the retroactively calculated Massey ratings for those teams. No way to leave him off a Top 5 list...
