There is a cruelty in the phrase "drive them off" that is detestable to me. Every coach has the experience of a player who because of attitude, personality, or some other issue makes them a bad fit for the team. Typically the coach will sit down with the player and have a series of heart to heart discussions about the issues. Coaching is first of all relationship building. The coach demonstrates concern for the player and works to inform the player of the situation and tries to resolve any underlying issues. Eventually the player may have to be told that it is in the player's best interest to try another venue. To drive off a player leaves the player without understanding of the core issues causing the player further pain and hardship down the road.
