Last year was difficult for the Shibs. Alex grew like a weed but Maia didn't and they looked awkward as can be out there. Fortunately, she grew last summer and voila, they look like an ice dance team again.
No range? Like alilou said, give them time here, certainly doesn't mean they won't get it. They are both stars, imo, and I can't wait to see what they come up with next. They are just going to have to work through the sibling thing, though. The Kerrs did it, so can they.
