Rock the boat?

I have been asked to coach on the JV high school squad i my home town.. Great! My problem is the way they run the practice and the way the season ends up. Both leave alot to be desired. I belive in coaching the techniques and fundamentels, I have watched some of the practices in the past seasons and I cant imagine why the DQ has no stations or drills at any time durring the week? The entire squad runs scrimage every day! Durring a game the spotters up stairs crittique the players asking why cant they do this or that? My conceren is that the defensive staff is not up to par . the DQ runs a type of defense that does not require any adjustments to a shifting offense. "W.T.F." I wish to coach but I'm not sure if I should speak to the HC of the program? I think its time for this program to clean house and the A.D to get some quality coaches on staff. Th youth program that feeds the high school sends some very good talent to the school, I and a few coaches were involved with the youth program for over ten years, several youth super bowl titles and even a couple youth nationals titles. The HC of the JV squad is in his second year and is a good friend of mine. The varsity HC hands him his staff and has allowed him to bring in a few new coaches, what should I do? What would you do?
