Six NBA coaches, including the Nets' Lawrence Frank, have been invited to give a coaching clinic outside of Chicago to honor the late Cotton Fitzsimmons, who died two years ago. The six--Frank, Jeff Van Gundy, Avery Johnson, Gregg Popovich, Flip Saunders and Mike Fratello--will instruct junior high school, high school and college coaches at the Moody Bible College September 15 and 16.
