There isn't much crossover.
Hockey fans, especially NHL resent the lack of coverage they get in cities that aren't Chicago, NYC, Buffalo..
Hockey is its own culture entirely.
Seattle got a team because it's a diverse city with a ton of Canadians, who will at least go watch their own teams visit. California transplants have 3 teams even.
And if the Kraken aren't competitive within a couple years it could still get ugly for them.
