Reminds me of something David Shaw (Stanford HC) said recently

"A head-coaching job has something to do with football, but everything else takes much more of your time: managing people, dealing with alumni, dealing with athletic directors and presidents and provosts and other on-campus personnel, setting schedules, handling difficult situations, handling your team individually and collectively.

"You can be a great X's and O's coach and lose your team because you made a couple of bad decisions. It's like showing you can climb a ladder and then trying to climb a mountain."
