1. 6 feet. Know it. Keep it clear. Use it.
2. Live-ball UNS foul by A7 (formerly A21). Penalize 15 yards (or 1/2 distance) from the previous spot and repeat the down. Add 1 to A7's UNS counter.
3. Charge a T/O to Visitors before the kickoff. Give 'em the full T/O if they want it. Play the kickoff down, and then penalize Visitors 15 yards at the succeeding spot (on the try, or succeeding kickoff, if a TD is scored, at the option of the offended team). This is a team UNS, so no player gets charged with this on his UNS counter. (Curiously, I just noticed that the penalty statement actually say that the Home team has the option to penalize on the try or the kickoff. That can't be right. Gott be the offended team. Right?)
4. False. Referee notifies the home head coach that the visiting team's headphones aren't working, solely as a courtesy to the visiting team. Play then continues immediately. Team communications equipment is not under the jurisdiction of game officials.
5. False. If there is nothing wrong with the ball that is in the game at that moment, the game ball shall NOT be changed.
