That is, to say the least, a peculiar statement about Hermann. He literally says nothing bad about her or what she did as AD, but he fires her anyway. (Contrast that to what he says about Flood, where he cites "struggles on the field" and "several off the field issues.") Assuming there isn't something bad in the investigation about her (in which case Barchi will look pretty stupid, and since he presumably knows what's in the report, I doubt he would let that happen), it's hard to read this as anything but "major donors said they wouldn't give if she stayed."
I have mixed feelings about the decision to hire Hobbs as the permanent AD. Compared to the people in the last round - including Hermann - he does not have a lot of experience, and he literally has no experience with a D-I football program. That troubles me, and raises the question of whether this was a political hire more than anything else. On the other hand, making a permanent hire now simplifies things and avoids the possibility of hiring a football coach the permanent AD wouldn't like or the chance that the process of hiring an AD would eliminate good candidates for the football job because it would take too long.
