Jay Williams aside we haven't really had any incidents in the NBA either, and he wasn't in the bubble. The NHL's bubble is very elaborate, multiple buildings, hotels, restaurants, and the arena, they can't even leave the area.
Canadians are nice, but they also have a functioning governmental and scientific establishment.
It would definitely be typical Flyers if they win what is still sort of an asterisk Cup. But it was a full season, and this will be a full and difficult tournament. I just don't think I'll be able to enjoy it in the same way, never mind that there also can't be a parade.
A long way to go, but the seed is certainly worth something. It's unfortunate they'll have to move to Edmonton, but smart they start that with the conference final, both teams will be on the same footing and whoever advances should be fully adjusted by the Cup finals.
