How are penalties assessed for illegal blocks during a change of possession?

When addressing the assessment of penalties for illegal blocks during a change of possession, the rules are clear that such infractions typically result in the enforcement of a 10-yard penalty from the spot of the foul. This is consistent with the NFHS Football rules, which mandate that illegal blocks, particularly those that occur during critical game situations like a change of possession, are designed to discourage actions that could lead to player safety issues.

The rationale behind this penalty yardage is to maintain fairness and promote sportsmanship in the game. By penalizing a team for an illegal block, the enforcement aims to negate any unfair advantage gained through the foul and to uphold the integrity of the play.

In this context, other options do not align with the established penalties for these specific fouls. For instance, although other penalties might involve different yardages or application points (like a personal foul penalty that might be 15 yards), they do not apply to illegal blocks during change of possession. Thus, selecting the correct answer embodies the enforcement expectations laid out in the NFHS rules regarding such infractions.
