That's a good observation. Too often we get so wrapped up in the performance of their team that we forget that they're real people.
During the debacle of the last few seasons in Nebraska, some people chose to view a couple of the coaches as ONLY existing to coach Nebraska. Our old DC's kid got heckled at a high school baseball game, and in every paper and news forum, people were screaming for the heads of everyone on the coaching staff in some pretty unpleasant terms. These guys did NOT belong here in Nebraska as coaches, but that's on the field. Off the field, Coach Callahan Charities raised hundreds of thousands of dollars for breast cancer research, Coach Cosgrove was a frequent contributor to his son's high school coach's learning curve, and the rest of the staff were reasonably active in the community, in local churches, and in keeping our players in the classroom with good grades (for the most part).
Just because a coach is not best-suited to lead this or that team, it doesn't make them a horrible person, and they certainly don't deserve to be vilified on the streets as the worst thing to ever effect the school.
