Trying to please the LRC gang is a no-win situation, because, as is sometimes said on this board, haters gonna hate, no matter what the reality is. Kudos to both Kara and Des for their noble, and worthwhile, and impressive successes. Des might agree that her voice is not as announcer-friendly as is Kara's (and the "haters gonna hate LRC posters will continue to carp about annoying voices), but what came out of each announcer's mouth was informative, from an expert's point of view, and observant.
So, Kara and Des, a tip of the hat to each of you.
No doubt, NBC will have their suits come up with their own reasons to either continue using you or to toss you aside, but sometimes such decisions are hardly based on common sense. So high-five your close friends (or fist-bump them, in these COVID times) and feel great about what you have accomplished in front of a mike.
