Hiring authority? In the Auburn situation the AD went rogue and hired Harsin while the BOT had other candidates they wanted. Another Blake James type case.
If I may...
this whole "blah and yada went rogue" narrative is a touch overstated (ok, completely so). Organizations just don't function that way, or at least as some want to believe that teenage angst drama club movies-of-the week portray.
Blake James, Auburn's AD, Fred BagODonuts down the street are not medieval warlords who carve out territory far from the King's castle and are able to hold it because of their own army.
Pure fantasy.
James (all Uni's AD or other executives) operated as Miami's AD in his manner because the President AND BOT allowed it/enabled it either by comission or omission...including the now famous "Columbus Crew" faction. There are no other facts on this, it's really that simple.
NOW, the ADs may act in manners where the President/BOT desire outcome 1, but the AD has selected outcome 2. This happens because the President/BOT have delegated/ceded those decision authorities to the AD (i.e. "we preferred X but we trust our AD to make decisions and he went with Y..."). When all is good, everbody looks like geniuses (even those silently gnashing their teeth because "their" choice wasn't picked).
When all goes bad, "going rogue" really becomes a euphemism for "we [President/BOT] gave the AD (or Coach) all the rope to hang himself with now we are going to yank it".
IF Manuela had gone say 10-2 last season, guess where HC Super Mario would be today--not Miami. If Harsin had done the same, this thread wouldn't have even started. Like with the ill-fated James/Diaz love story, it sounds like Greene/Harsin could (is) going the same way, although Bruce Pearl putting the Tigers in BBall's pole position probably helps to save him [Greene].
Since I'm a tangential kinda cat...why the **** does Miami still have Larranga and not a Pearl-esque Bball HC?? Is that Rahd the Impaler's plan once football gets started on better path?
