You appear to be right about Garza. It is my understanding (TOS) from those close to the program that Garza wanted to stay here, but was told by Coach Dooley that his retention would be completely up to the new DC, whoever that might be. Knowing that most Coordinators prefer to pick their own staff (as they should), he knew that his career here was hanging by a thin thread. Because of that, he would have to take any good offer he got, even one from kiffin.
From what I understand, Willie Mack was completely up front about his situation with recruits, telling them that he might not be here for long -- and that specifically included his recruitment of Hunter, with Dooley sitting there. He was honest and up front with all the recruits (as he should have been) and that is all we can ask. That is also why his leaving has not had a big effect on his recruits, including Hunter.
I also think that Coach Chaney and Coach Thompson are all Vol, and will coach our guys to the best of their considerable ability.
