Positive Coaching Alliance (PCA), a non-profit dedicated to transforming youth sports, annually releases the "Bottom 10" list of the worst behavior in sports from pee-wees to the pros to stimulate discussion among parents, coaches, players and educators.

To facilitate teachable moments, PCA also released its "Guide to Discussing Sports Incident s with Children," a practical tool that any adult can use to help youth athletes avoid imitating bad behavior and encourage them to emulate the many inspiring and uplifting examples that sports produces.

The entire Bottom 10 list, Top 10 list and Guide to Discussing Sports Incidents with Children, including links to video of many incidents, appear at http://www.positivecoach.org/Blog.aspx.
