According to money guys I know, we nearly lost Gary to greener pastures a couple of times in his earlier years. I remember a tense discussion these guys were having at the Salt Lake City Marriott concierge lounge the morning after the tough 2008 loss at Utah about needing to pony up more money. I believe that Gary made the TCU job so good that it just didn't make sense to leave for places where he would be puppeteered to varying degrees. We kept him and he stayed with us because of ours and his lucky stars..
We hope not to become a stepping stone but that's just difficult to do.. For goodness sakes, LSU lost Saban for greener pastures.
Regarding Deion, I love the idea of instant recruiting and starpower, but I'm afraid he's only around for the good and won't have a work ethic and when things get a little tough, he may be gone or just won't perform admirably.
