Seattle has a pretty fantastic history. Now, I used to live in Portland so I want to preface this by saying that Seattle people are all losers and wankers but they have a fantastic (and highly beloved) coach in Brian Schmetzer and a pretty proud history.Jag är lite nyfiken på Seattle, sedan Suarez/Miami-incidenten, och för att jag följer Kraken i NHL.
They won the MLS cup twice and are one of the very few US teams to win the CONCACAF Champions league which is what got them their ticket to the club world cup. They didn't win anything there but they played 0-2 against PSG with a 51 million dollar squad which is hardly a shame.
I believe the only team to have won every trophy available to a US team at least once.

Big support at games, usually 30k at home matches.
Cascadia / Pacific North West has always been a strong football region: Cosmopolitan, left leaning places with big immigrant populations and a general feeling of only barely being part of the US (and literally so, given the Rocky mountains).
The traditional rival is Portland (exemplified by the "red card wedding" game I linked a clip from a while back where Seattle finished the game with 7 players at the end) though both teams also consider Vancouver as a rival.
There is a separate Cascadia Cup, created by the fans, which is awarded based on the regular season outcome of games between Seattle, Portland and Vancouver.
They have games left against LA Galaxy, Miami (which should get spicy), Austin, Vancouver, Portland, Salt Lake and NYFC.
The Galaxy game is listed as being on Apple TV+ if you have that.

The 5-2 battering of Kansas City from a few weeks ago
Oh my, how did this 0-3 defeat to the Whitecaps sneak in here? Awful stuff really

Anyways, yeah, Seattle is totally fun as a team.
