if we were watching football or basketball or soccer or basically any other sport, the announcer wouldn't have to explain every fucking rule of the sport during the match.
Why should skiing be any different? Especially on webcasts, when basically the entire audience knows whats up. Announcers should focus on calling tricks correctly, especially with regards to natural/unnatural spinning directions, and not just calling every double off-axis spin a 'double cork', and not even bothering to tell the audience how much they spun, or whether it was a true double cork, or a double bio, or switch double rodeo, whatever. Surely it cannot be that hard to do this, I would imagine the vast majority of this sites members could do a better job calling tricks and commenting on cleanness of landings/style/grabs etc.
Step your game up announcers.
