Boca,
I seriously doubt that Self had 56% of the players that he recruited leave his program in any five years sequence of his career. With that kind of turnover, you are not going to win and you will find yourself recruiting in desperation which is why we have a team that fit better in the Southland Conference.
As for Assistant Coaches, I promise you that Self has never had to hire his video guy as an assistant nor was his staff only experience in low level conferences. That is the case with Capel's current staff. As I recollect, Billy Gillespie was on Self's staff at Tulsa and Illinois.
The bottom line is Capel found lightning in a bottle with Blake Griffin and now his bottle is empty.
