Why aren “roughing,” “running into,” and “interference” always fouls?
Use these actions to describe contact that wouldn’t ordinarily constitute a personal foul. If a player roughs an opponent who’s not the passer, kicker, holder, or long snapper, it’s no foul. The same goes for running into anyone but the kicker, and interfering with anyone but a pass or kick receiver. If you want to describe conduct that’s always illegal, use “personal foul” instead.
