Coach-player relationship is beyond the difference of opinion both of them may have. Dispute with coach will remain as a black-page in every player's history, no matter how skillful he or she is. A given player may look important at the given moment but inclusiveness is important at any moment!
Handling the situations between coach and player is not an easy task. And the best people who can resolve that are the coach and player themselves. Whatever said and done, there can be a situation that leads to the ultimate decision. How that whole decision process happens and what happens post the decision process elevates the integrity of everyone involved.
