I have to say I am a little surprised at the extent of the cleaning house by Bustle. But, I am impressed that he did it. I have seen far too many coaches hang onto their assistants in the midst of less than satisfactory performance. Whether or not you believe the results can be improved by simply changing out assistants, it is the first major step a head coach must do.
I concur with the person who said that this action is a sign that Bustle wants to succeed, rather than enjoy the company of people who he may like, personally. The message has also been sent the players... our head coach says that you either perform, or someone else will. I am not saying that this message (to the players) needed to be sent. But, in good programs, the coach needs to be viewed as a person who will replace you if you do not show a total commitment to success. Along those lines, this is a message to new recruits that this coach will play those who get the job done.
I like the move. But... I am curious to see who replaces these assistants... and wonder if Bustle had that planned out before he cleaned house.
