I think when some people critique commentary (which I'm guilty of, don't giet me wrong), we tend to focus on comments that the commentators probably didn't put too much thought into at the time. Like when Sumners called Sasha unbeatable, it was probably just a passing comment that wasn't supposed to be analyzed. Of course Sasha's not unbeatable, no one's unbeatable (except maybe plushy....but that's a different story.) The commentators are people, and they'll say things they don't mean, and they'll say things that aren't necesarilly true all the time.
One thing we have to remember is that we are all pretty knowledgable figure skating fans. We can all tell the differences between the jumps, and we know what a flutz looks like, and we can find mistakes in seemingly "flawless" jumps. However, what we need to remember is that Dick and Peggy and Terry and all the others are commentating for the average watcher of figure skating. It's their job to keep people informed of the things that are going on in the program. If you think about it, we don't need commentary. I could watch an entire skating program and know exactly what happened...but a lot of people aren't like that. My dad, for example, has watched skating for years, and he can't tell the difference between an axel and a lutz (um...that's the one with the toe, right?

) My dad adores Dick Button because he keeps him informed about whats going on. My father doesn't need to know that Sasha's lutz was actually a flutz...because that wouldn't mean anything to him anyway.
We can bitch about the judging (and I'll do that as well), but the commentators are just trying to get paid. And their job is to keep people entertained, and, in my opinion, they do that perfectly.
