I wonder if the powers that be realize how open-ended this rule reads. As constable said, it would put all PA announcers out a job if interpreted strictly.

Maybe NFHS will issue a case play for this to help clarify.
Maybe it's better I'm officiating now. A few years ago, I did stats for a pro-am league and was required by rule (modified NBA) to do the 2 minute announcement and it has stuck with me ever since whenever I've been on the mic.
Fortunately, I doubt I'll have to address this in the next game I officiate... MS girls next week.
