Realistically, I cannot agree that this cost Tim Boeckman his job. The ONLY thing that costs coaches their jobs is not winning enough football games. If Boeckman had taken the Illini to the Rose Bowl, you would never have heard a word about that.
A number of years ago, when Nebraska fired the successor to Tom Osborne, Frank Solich, I started hearing about all this stuff that he had supposedly been doing. But it only came to light when one of Solich' teams went 7-6 or something like that. Then and only then did "this other stuff" matter.
In the same light, if James Franklin has a bad season and loses too many games, this will come up and you will hear about how this contributes to his firing. But I don't believe a word of it. Franklin wins, he stays - he loses, he goes - no matter what.
By the way, no I do not believe KFz pressures medical staff to get injured players to play. I'm sure he presses to get as much information as he can so he can know whether he will have that player or not. There are two things to watch there (at any school) - one is how coaches treat concussion sufferers (in the days before the concussion protocol) - the other is whether there are any "game-time" decisions regarding players. Iowa has had many players warm up but ultimately have the decision made to not play. There are some downright legendary coaches (especially in the pros) who were the worst of the worst in terms of making concussion sufferers play.
