It occurs to me there's probably a significant percentage of people being critical in this thread who watch between 85-95% of their Kings games on the Kings' broadcast, and tend not to watch other teams at all when they're not playing the Kings. Sideline reporters tend to not be very good anywhere; even the very best aren't very good, and none of them are particularly essential to the game.
I think that it's a fair criticism to say that most of her live segments have been awkward; I happen to think that her post-production stuff, like the "perspective" segments, have been quite good. I think that appearing to not be aware of Arco's history of being very loud is fair criticism, but not not to the level that has been expressed here.
You know what would really be cool? If the people who think that she's not doing a good job offered something more constructive than "OMGZSHEISTEHSUX0RSLOLWTFBBQ!!!!!111" I mean, it would be different if she'd been doing this for twenty years... or, hell, even three years. But what she's doing now, judging by a quick glance at her website, doesn't seem to me to relate directly to anything that's she's done before. Maybe it's just me, because I've always worked in technical jobs, but I've never met anybody who'd mastered their job in a year. If she's still making rookie mistakes next year, that'd be one thing, but people seem to be holding her to the same standards as sideline reporters that have been doing that for years and years.
