I used to board op Sox games at a White Sox Radio Network affiliate.
In between certain innings that are specifically designated, we would have to play local commercials, PSA, weather, etc. At any radio station at any time of the day someone is always calling and distracting the on air guy constantly. Thus jeopardizing hitting the air cues, legal ID and breaks. It is always better to have two guys on hand.
One of the best calls we normally got during a Sox game was somebody wanting to talk to Ed or DJ. Or somebody calling in every 15 minutes to get the game score. Turn on your radio!

One night during a pregame show, Rongey's mic was hot during the breaks. This went on for a few breaks and you could hear Ranger talking about this and that under commercials. I tried to call The Score studio but nobody picked up. To Rongey's credit, I never heard a curse word or anything that deemed inappropriate.
