I guess the Russian system is different from the American one, because Griazev has been taking part in both the junior and the senior Russian Nationals since 00/01 season. Laste year he as 5th at Senior. So he will certainly be there at seniors; the only question is -- will he be at juniors as well.
Don't you just hate it when they post photos of medal ceremonies and there are no people in the stands? I know it's a limited view, but the impression it leaves is that there was no audience!
