Diligent coaching starts and ends with teaching players responsibility from a team and individual standpoint. Every player in an athletic program must be taught team philosophy, team strategy, proper interaction with other teammates, respect for the opposing team and roles for each player on the team depending on talent level.
It should be explained to athletes on the first day coaches and players are together that any deviation from the team concept will hurt the performance of the team.
Where accountability comes in is when players knowingly or unknowingly break team rules. Young players usually have not been in a true team setting and do not know how to be teammates.
It is up to coaches to find out if players can be great team members or if they are more suited to individual sports such as golf or tennis. Coaches should not accept excuses after explaining and demanding team play. If players are not accountable for their non-team actions, parents should be informed immediately when such behavior is seen or identified.
