Once upon a time someone decided the San Jose Earthquakes and Seattle Sounders were rivals. This was not the people who founded the Heritage Cup. Those people thought that the ‘Quakes and Sounders had a mutual heritage that deserved honor and respect. Someone else decided about the rivalry talk, which is weird. The record between the two clubs kind of indicates a rivalry. San Jose dominated early going, but it’s the Sounders who control now. They haven’t lost to the Earthquakes since June of 2016 and haven’t lost in San Jose since August of 2014.
