It is a very tempting thought indeed- to kick Czisny off the World team for this atrocity. I bet certain other federations wouldn't hesitate to do so...
But upon further thought- you kick Czisny off the team and replace her with who, exactly?
....
Zawadzki? Don't make me laugh. She is just as inconsistent as Czisny is, and worse, she doesn't get the scores Czisny does (yet). This is clearly a step down.
Zhang? After 4CC this might be tempting...but Zhang was quite solid at both Nationals and 4CCs. If she has a bit of an off-night (happens to everyone)? Not sure she has much to hold her up if that happens. I think it would be a serious gamble.
Nagasu? Well, not after what we saw at Nationals. Her head clearly isn't in the game and I doubt she's training actively enough to be ready for top-level competition in 2 weeks.
Gold? She has not skated a senior program all year long, and while it appears she has SOME mental toughness, still a lot to ask of anyone to get ready for big worlds in just 2 weeks time. Anyway, is 2 weeks enough to get a senior LP trained and ready to go?
Flatt? Well...let's just not go there (again).
