We seem to have gotten off the topic here, Patrick Chan saying nice or nasty things about his competition, Patrick Chan being a good or bad sport (and the same goes for everyone else) does not make him a GOAT. The leading lights, the absolute geniuses for the ages in many fields have sometimes been unpleasant people and said (and did) unpleasant things. It's harder to get away with it now, because the acoustics (and the audience reaction) are different. On the other hand, some of the geniuses have been perfectly lovely people. That doesn't make them more leading light than the rotters.
What could be looked at is GOATs on a national level: is Chan that for Canadian men, or is Browning? Kwan would take the US women, Yuzu Japan, Yuna Kim definitely Korea... Russian women, god only knows.
