We'll have to wait and see how Barkell does with Miyahara and Zhou, but Dalman hasn't benefited all that much yet. Who knows? I don't think he's going to help Satoko's UR problem and probably not Vincent's, but maybe. She's a lot younger so maybe he can improve her UR issues. Or not. But, since he's in Canada and she's not, it's a moot point right now. Very few skaters can do what Nathan and Raf managed.
Wasn't he Daleman's coach when she won bronze at the World Championships? IMHO Daleman actually has great jumps when she's well trained.
