I happen to believe that a fundamental responsibility of the announcers (usually one play-by-play and a partner doing analysis, often backed up by a third person on the floor) is to prepare. Before going on air, they should do their homework, which includes study of the rosters to make sure that they know how to pronounce each player's name, where s/he is from, plus interesting or pertinent information abour each of them. When they come up short, I think it is fair to call attention to it. There is an Ignore button for those who disagree.
