Seattle Sounders FC's rivalry landscape extends beyond their primary rival (Portland Timbers and Vancouver Whitecaps). Conference opponents who regularly compete for playoff positioning develop competitive tensions over time. Geographic proximity creates natural rivalries even when not officially designated.
Some of Seattle Sounders's most intense matches come against teams they've faced in the playoffs or competed with for specific trophies. These secondary rivalries may not have the same history as the primary derby but can produce equally dramatic and passionate matches.
