agree, as I had indicated.
Well, as a very senior exec who has done it myself, and having seen other critical senior execs do it, that doesn't always happen. But yes, most of the time they are walked out immediately. But your point about the HC being the whole team is why I'm arguing that they should have let him do it. When a normal company senior exec is leaving, there is plenty of infrastructure and resources in place to go on without significant risk of having a terrible near-term result. A head coach leaving most of the time torpedoes a team's chances, except for Michigan basketball Fab Five.
However, all of this may be a moot point. Given that Ole Miss just announced Golding as the permanent head coach, then it is now completely clear why they couldn't let Kiffin coach. They've got their permanent new coach and they immediately now need to go to war with Kiffin to keep as many players and coaches as possible. I totally get Ole Miss's move now.
