The good announcer will know what to do in each case. They will know straight away if they can do the gig or not and will state as such immediately.
So much goes into being a good announcer. First, the skilled public address announcer will be keen on knowing the game operations, scorekeepers, scoreboard operators, marketing folks, music person and officials. They will realize out of the gate they must interact with every last one of these people. Each plays a role during any contest. An announcer may have to check on fouls with the scorekeeper, jersey changes with game operations, coordination with the DJ, field games and promotions with marketing, procedures with officials and more, more, more.
A greenhorn will be utterly lost. Any announcer who has spent more than a smidgen in a press box or at a scorer’s table will tell you it is without doubt the most fluid environment on Earth. Things happen. The place is rockin’ busy. People come in and go out constantly. Only a skilled announcer retains the wherewithal to keep focused amongst the chaos.
But being lost is not so bad…right? Yes, except if you have 15,000 fans, rooters and cranks alike, in the stands, little kids running around, a packed press box, a tight ball game, marketing changing their programs on the fly, coaches dynamically modifying their player lineups, and maybe sketchy weather in the sky. Oops! On the other hand, the skilled Public Address Announcer will say, “Well, that’s just about every game.”
On top of it, the able announcer will climb on the mic quickly after a play and announce the result fluidly as if game operations had programmed it into his or her bloodstream. If the game needs to be suspended for whatever reason, he or she takes that data to the mic and calmly delivers an articulate message to the crowd to guide them out of the ballpark or gymnasium. They adjust quickly when marketing has modified their promotion at the last second yet, their delivery gives the appearance it was marketing’s plan all along. Pull someone out of the office or off the street to do this equal to a proper public address announcer and I attest we bear witness to a miracle worker.
