Who may be in the coaching box while on offense?

The coaching box is designated for the use of team personnel during offensive plays, and any member of the team who is not ejected for unsportsmanlike conduct has the right to occupy this area. This structure ensures that players and suitable team members can communicate and strategize effectively during a game.

By allowing any non-ejected team member in the coaching box, it fosters a supportive environment that can include assistant coaches, team captains, or even players designated to provide specific guidance. This flexibility helps enhance team dynamics and strategy formulation.

The other options do not encompass the broader range of individuals who may serve in these roles. Limiting access purely to the head coach or trained coaches excludes valuable contributions from other members of the team who can aid in the performance on the field.
