Who is in charge of inspecting equipment before and during the game for approval?

The referee is the individual in charge of inspecting equipment before and during the game to ensure that it complies with the rules and is safe for use. This responsibility includes inspecting players' gear, like helmets and pads, to ensure they are not only properly fitted but also meet the required standards set by NFHS regulations. The referee ensures fair play and player safety, which is paramount in football.

While the head coach, umpire, and team captain play critical roles in the game, they do not have the specific responsibility for equipment inspection. The head coach is responsible for the conduct of the team and overall strategy, the umpire focuses on enforcing rules and calling plays, and the team captain may represent the team in discussions with officials, but does not handle equipment approval directly. Hence, the referee is the correct answer as they are designated to oversee this aspect of player readiness and safety.
