They also didn't make more than one mistake in their 2 last seasons. Who does that ?
No one. Not even D/W. THAT is what is most irritating. D/W made plenty of mistakes in their final two seasons. They weren't docked for them. That's not their fault. That's the fault of the judges.
As for whether they could compete and win against P/C now, sure they could, if the judges judged the same way they did when D/W were last competing. But if the judges decided to follow the actual criteria, P/C would wipe the floor with them. To think Charlie's hockey style skating could even be in the same league as Guillaume's effortless glide is delusional at best.
