Besides wins and losses, I feel that one of the hallmarks of a successful head coach is one whose assistants go onto greater roles with other teams. With the latest hiring of Kevin Wilson at Indiana, this is a bit of a hat tip to Bob Stoops at Oklahoma. Considering he was hired in 1999, this is a pretty impressive string of HC hires from his staff. You can say what you want about some of the characters on this list, but it is still a list.
Mike Leach- HC Texas Tech
Mark Mangino- HC Kansas
Chuck Long- HC San Diego State
Mike Stoops- HC Arizona
Bo Pelini- HC Nebraska (with a short stint with Les, can count this either way)
Kevin Sumlin- HC Houston
Kevin Wilson- HC Indiana
This does not count the list of assistants that went on to become OCs or DCs with other major programs. I have no idea how he keeps reloading with that coaching churn.
