I am all for having as many good football minds as the NCAA will allow us around the program, particularly when it comes to game planning and game execution and stratregy.
But, at the same time, the coaches who are going to be handling the 'in game' play calling, substitutions, scheme adjustments, etc etc MUST be the very same ones who break down opponent film, analysis and tendencies. The Riley as his primary staff MUST be personally involved and putting all the work in themselves so they recognize and KNOW the details. You can rely on others to do your prep and study. Each game is like a big exam or test on the material you should have studied ad infinitum. If you are content to have others do your home work, you are doomed to miss those key questions and will blow it on the game day exam.
Finding and screening future players, doing the back ground on things, eval of past films and all that are great to have second and third and fourth opinions but they better really know whagt they are doing and better know our own strengths and weaknesses so they can avoid the disasters.
