I agree, Lori. But apparently it is too much. Even experienced fans can benefit from a quick recap like that, because in some of these sports, the rules change every year, and if you only see the sport televised at the Olympics, you may not know about the rule change. And that's not even counting the cases where the rules for Olympic competitions are NOT THE SAME as the ordinary elite competitions. NBC really needs to do better in Primetime. Even viewers who do know what they are watching appreciate having someone else pointing out what they should be looking for. I saw someone mess up a jump landing. So what went wrong? I wondered if he had landed with his weight too far back on his blade. Then Johnny Weir explained that the skater had landed with his weight too far back on his blade. So now I know I've gotten better about seeing what is happening. In snowboarding, I may also see that someone has landed with his weight too far back on the board, but I appreciate hearing from the expert about why that happened (e.g the timing was off because he opened up from the twist/somersault at the wrong moment). Snowboarding, figure skating, skiing, ski jumping, even curling -- so many of these sports are all about physics. But the basic principles you need to know are easy to understand, as long as you have someone who can explain them properly. Athletes are a mass moving themselves through space, or in curling and hockey, causing a mass to move through space. It's all about how you set that mass into motion, and how you keep it on the optimum path to go longer/faster/higher or to go where you want it to be. As Lori said, the basic rules / scoring should be given at the outset; after that, the more complicated parts like tiebreakers can be explained if they come up. There are some things that don't show up well when you are watching on TV. For figure skating, a TV-only viewer is not going to pick up the visual cues about how fast someone is moving across the ice as well as someone who has actually been at the rink and can translate their fixed-point experience of fast and slow skating to the TV-camera perspective. Ice dancing is one discipline that suffers especially from this -- it's difficult for the casual viewer to appreciate the difference in basic skating quality only from watching on TV.
