I caught up with some biathlon on Peacock and to my surprise there was a commentator, I think Chad Salmela. First year I’ve heard biathlon commentary on Peacock, as far as I can tell. I thought he did a great job, quickly explaining the rules, the stakes, who was in shape or not, racers’ background, etc. He managed to cram in a lot of info. For a casual viewer like me, he was perfect.
Re: alpine commentators. I’m a journalist in mainstream publications and I can tell you that each article is a constant balancing act: you have to not turn off casual readers while giving more informed ones a little something to chew on. Skiing is a niche sport in the US, so covering it is tricky. I think Porino and Schlanger mostly do a good job, though I prefer Porino paired with Ligety or my fave, Miller. (Vonn, on the other hand, was not good.) And they’re miles above the Eurosport commentators I heard while in France over the Christmas break. Completely useless!
