Successful places, not just football will lose talent over time as success is always poached. It is easier than development in house. However, the best places are not immune to staffing roll-over, rather it is healthy, the difference is that they hold onto talent, working at a high level for longer before transition. That is sustained success.
I think you hit the nail on the head. Welcome to the life of Bear Bryant, Bobby Bowden, Nick Sabin.... great programs spin out great coaches. What a compliment to Dabo this is. I think everybody takes a "chill pill" and watches our program in the playoffs next year.
