You really don't know what in the **** you are talking about.
A head coach leaves/retires/is fired. The AD's first actions are usually notification (including the university president and BOT) and then a search firm is often retained. There are often multiple names, but the search COMMITTEE (with the AD having disproportionate influence) will interview the names and make related decisions.
What almost never happens is an AD then going to a BOT (and/or any of these boosters you keep yapping about) and saying "here are my five candidates, please tell me which one to hire".
If boosters EVER have any input, it is prior to the decision-making process. The boosters may say "We'll help you fund the buyout for Candidate X if you hire him". Or maybe there is an obvious candidate, often someone with prior ties to the school, or a "can't miss name" like Urban Meyer or Nick Saban.
But, ultimately, the DECISION on who to hire is with the AD and the search committee. The BOT is there for final authorization (and very rarely, a veto). This is the reason why the buyout, the interview, the extension of an offer, and the signing of a contract do NOT all happen at the exact same time. Things take time to get done, and most frequently the HIRE of a new head coach is done with a letter of intent, and not a full-fledged, final, and BOT-approved contract.
The point is, you made a very definitive specific statement on Blake and the hiring of Manny, and when people called you out on it, you started defending yourself with general comments about "boosters/board at every major power 5 program".
Nope. You don't get to make a factually incorrect statement about UM's actions and then try to claim some generalized knowledge of what other programs do or don't do.
