At that level, it's really a political issue. On a Saturday, Eddie Sutton went on CBS and said he intended to remain at Kentucky. The next morning David Roselle, then UK President, called him and said "I've got the votes Eddie." So Sunday afternoon Eddie went back on CBS to say "I have decided to resign my position as head basketball coach at the university of Kentucky." Roselle had talked enough board members into siding with him such that he had a majority of the votes, so no one was going to stand in the way of firing Sutton.
In Louisville it's been an open secret that the interim president at Louisville, Postel, wants the full time job, but the athletics department (Pitino, Jurich, etc.) doesn't want him to get the job because they don't think he is supportive enough of athletics. (What that means is they can't count on him to let Jurich do whatever he pleases like Ramsey and Shumate did.). Postel has the support of the UofL board, and persistent rumors say that David Grissom, the board chair, told Postel to fire Pitino this summer. But his buyout is $19 million, too much for a cash strapped school. Now presumably they can fire him with cause, and won't owe him the 19 million (although practically they will agree to pay Pitino several million not to go thru a lawsuit). So now, presumably Grissom and Postel can get to the ending they've wanted.
