I've been meaning to point out how good Johnny Weir has gotten in his knowledge of ice dance. He's always been a very good commentator of figure skating. His skill as a commentator when he's with Tara is lessened a bit because she eats up so much air in the booth, and both Terry and Johnny are protective of her. She always needs to take things down a notch. They all three have a good rapport, but Tara too often overtalks. With Tanith (who is so good in her commentating and in her knowledge of ice dance), it's obvious that things flow more smoothly, and Johnny is able to show off his commentating skill better than when Tara is in the booth. He has no need to compensate or be protective of Tanith who more than holds her own. I can tell that Johnny has worked diligently to learn more about ice dance, because he didn't know much about this discipline when he first began commentating.
I noticed how good Terry, Tanith and Johnny are together commentating ice dance, at U.S. Nationals this year.
