What is the penalty for slapping a blocker's head during a football game?

When a player slaps a blocker's head during a football game, this action is considered unsportsmanlike conduct or a personal foul, depending on the specific context and intent. The correct penalty for this type of behavior in high school football, according to NFHS rules, is 15 yards.

This is due to the emphasis on player safety and sportsmanship within the game. Actions that are deemed to be aggressive or disrespectful against opponents can result in substantial penalties to discourage such behavior.

In contrast, lesser infractions related to technical rules of the game, like false starts or offsides, would incur lighter penalties such as 5 yards. Therefore, the penalty of 15 yards is appropriate for actions that endanger player safety or compromise the spirit of the game.
