Always came across as a guy who got to where he is not based on merit and truly top notch job performance, but someone who is simply a master of positioning and politicking.  To me, his in-action during all of this tells me this is true.

Take credit when things go well to move ahead, blame others and duck when things are going south... never maintain any level of accountability for anything that might be bad for your image.  Hard to imagine anybody thinking they can be successful in a job like that without being accountable... even just some shreds of honesty acknowledging some of the mistakes and steps to be taken to not make those mistakes again would go a long way.  He's clearly too stubborn to realize.  Even if it's simply a perception that he messed something up, he should be in tune to that.

Only difference is this time, this may finally be too big for him to duck... shareholders care about their company's performance, but a company struggling because they put out bad pizza is nothing like the lightning rod for negative PR that the UM football program is right now.

I could see how it would be delaying things, as I assume the medical staff would then have no choice but to go above the AD to the president or whoever the next higher authority is until they reach some satisfactory resolution.  I would also commend the medical staff for having the fortitude to stand up against the idiots running the athletic dept.
