Why Can't Sportscasters Just Shut Up?

This is not the first time this has bothered me.

Andre Agassi lost the final point of his match with Ben Becker, ending an amazing career in tennis. I was sorry to see him lose.

The crowd broke out in a spontanous ovation for Agassi that went on for some time while he remained seated. Andre was in tears. He was overcome with it all. The moment was as emotionally charged as any I've witnessed on TV.

And what do the sportscasters do? They proceed to TELL us how emotional the moment is - babbling inanities so pointless as to all but kill the moment.

Look, I get it. Announcers are supposed to announce. But they are supposed to help us appreciate what we are watching. Not become what we are watching. I appreciate their babble during the game. It helps me understand some of the finer points of technique, of history, of "human interest" etc.

But somethings just don't need to be explained. Some things do all the talking that's needed all by themselves. Who needs commentation on such moments? Wait til it's over, or nearly so, and then babble away. Anyone who didn't understand the moment was an emotional one, by that point wasn't going to get it from anything the commentators had to say.

Why can't they trust us to experience an emotional moment by ourselves? Why must they usurp that time. Is it an ego thing? Is it policy? Why can't they just shut up and appreciate the moment with the rest of us?
