The player handbook is considered:

The player handbook serves as a confidential agreement between the coach and players. This document typically contains essential information regarding team policies, expectations, rules, and guidelines that players are expected to abide by throughout the season. It establishes clear communication between the coach and the players, fostering an environment of mutual respect and understanding. By treating the handbook as a confidential agreement, it emphasizes the commitment of both parties to uphold the outlined standards, thus creating a structured and focused team culture.

Other options may suggest that the handbook is intended for different purposes, such as sharing with parents or being a summary of the season, but the core function is to establish a formalized understanding between the coach and the players. Additionally, categorizing the handbook as optional undermines its importance in guiding player conduct and team operations.
