Who qualifies as a non-player during the game?

In the context of NFHS football rules, a non-player during the game includes individuals who are not actively participating in the game, specifically coaches, trainers, and substitutes. Coaches are part of the team personnel who guide and instruct the players, while trainers assist in the players' health and safety. Substitutes, although they might eventually take the place of a player on the field, are classified as non-players until they enter the game to replace a player. This definition ensures clarity regarding who is allowed on the sidelines and the roles they play during the match. Other options might limit the definition unnecessarily or incorrectly include individuals that do not fall under the official non-player categories.
