Illegal? Or just odd?

[MD Longhorn]

Calling a 7th grade game last night under NCAA rules. Believe it or not the guys had a PA announcer working, and as it turns out a very active one.

I don't believe I've ever heard this before, but this guy was obviously a radio announcer wannabe, and was giving play-by-play DURING the play! I found it strange, but couldn't recall a rule against it. The more I thought about it, the more it bugged me. Final straw was when one team ran a reverse. The play ran away from me, and the herd of 7th graders ran that way too. Then just as it starts coming back to me, I hear "It's a REVERSE!"

Now I'm not positive whether anyone on the field actually heard him - but if someone on the defense did, and acted on it, that seems to me against the spirit of the game.

Someone tell me where I can find the rule that would forbid this - it's GOT to be illegal.
