If you build up a program to a certain point, support it and the coaches you bring in, then you can attract good coaches that want to stay.
Stanford and Duke are good examples. Harbaugh came in, recruited well, and built up Stanford to win consistently. Now Brian Shaw is maintaining a good program there, and he's been on many factory schools AD's lists and NFL lists over years but chooses to remain at Stanford because they maintained a program that Shaw finds attractive to put roots down.
Say what you want about David Cutcliffe, but he has raised the level of play for Duke. Duke has rewarded him and supported him enough that he's turned down several jobs over the year...he turned down Tennessee multiple times and that fanbase worships him for what he did with Peyton Manning, Tee Martin, and Heath Shuler.
Point is, GT can be one of those places. In this era, if a coach stays 8-10 years, that's considered a long time. If you look at what Stansbury is doing, he's putting things in place to attract good coaches and giving them reasons to stay. Giving CGC 7 years and all that money, and all the social media support isn't just helping CGC...it's also advertising for the next coach that GT is upping the game and doing what we need to do to bring in and support good coaches.
