Yes, why fire Blake if you will just hire an underling? Obviously you are firing him because you do not agree with the direction of the department and want to bring in someone new. Even if she was made "interim AD", I do not see her keeping the job - just like very few "interim head coaches" get the permanent title.
The difference in this James scenario is Eichorst wasn't fired. He left of his own accord. That is the difference and therefore, there is no pattern.
You mentioned in your prior post that Miami would want to be part of the "progressive" ACC and hire a female AD. My point was, if that were the case, why didn't the ultra-progressive Shalala hire a female AD when she had 3 opportunities to do so? Again, politics doesn't need to be put into everything.
