I read this story on the tweets the other day, and commented on it in one of the other threads.
I think what Washburn was alluding to is not only is there not enough NBA experience on the coaching and front offfice staff, there isn't enough African American presence, especially with McCarty and Strawberry leaving. The NBA is 85% African American players, and the Celtics' staff needs more African Americans on the staff for better communication with the African American players.
