Figure Skating on NBC, and before that on ABC, has always have commentary like that. They speak over the music, because when the music ends, they go to ASPCA ads!
It's not even because they're network TV, really, tried to watch the Russian EuroSport stream? OMG!
I noticed that Weir actually stays quiet for prolonged periods on a program, which no one else on network TV sports broadcast ever does, and surely NBC doesn't pay him to stay quiet.
Tara talks a lot more, Sandra babbles a lot more, and Scott screams and grunts much more than Johnny talks.
I enjoy team Terry Gannon and Johnny Weir, pity they won't be in the main broadcast for the big competitions.
