In which situation would a player receive a 15-yard penalty and possible disqualification?

A player receives a 15-yard penalty and possible disqualification for violent confrontations with an official because this behavior is considered a serious violation of sportsmanship and respect for game officials. The rules explicitly protect officials from any form of aggression as it is crucial for maintaining the integrity of the game. When a player confronts an official violently, it undermines the authority of the officiating crew and can escalate into more severe situations, hence the heavy penalty.

In contrast, unnecessary roughness calls typically result in a 15-yard penalty but do not inherently carry disqualification unless they are particularly egregious or involve fighting. While multiple illegal motions may lead to penalties, they do not accumulate to the level of disqualification or a significant yardage penalty. A delay of game infraction results in a loss of five yards, which is much less serious than the potential consequences of confronting an official. Thus, inflicting penalties on player decorum and the respect owed to game officials is a critical aspect of ensuring a fair and orderly game, justifying the severity of the penalty in this case.
