This is shocking to me. My brother is a retired college football head coach. Two of his sons are acclaimed college football players. I've spent time with the head coaches of two teams currently ranked in the top 10 in the NCAA. I've been around the sport for decades and know how coaches' lives can be monopolized by the job. To see an NFL head coach doing something requiring this level of time commitment blows my mind. I guess it's a reminder that to reach the very top level of a sought after profession, you have to be a remarkable individual.
