This is not going to end well.
In regards to the makeup of the staff, it's kind of hard to argue with the most winningest program in the decade, numerous Top 10 recruiting classes, numerous coaches attending the Duke Coaches Clinic and reporting benefits from learning from the best, putting the most players in the NBA with the highest salaries, etc.
Although, things can always be better, and there are always areas to improve on. I'm one to not just cast someone aside in order to get something (hopefully) better, but rather improve the people that you do have and make them better. Change by omission is not necessarily a good thing, but making things better is always good change.
