FWIW the 2021 Seattle Mariners ranked in the middle of the pack of American League attendance (although Toronto's attendance was artificially low because of travel restrictions).
Indeed Seattle has MLB's longest current postseason drought at 20 years despite a better cumulative regular-season record than nine franchises over that period. The postseason has eluded the Mariners despite seasons of 93, 93, 90, 89, 88, 87, 86 and 85 wins since 2001.
This poster was a hardcore Denver Bronco fan for 20 years but lost interest in the NFL altogether after the Broncos won back-to-back Super Bowls in the late 1990s. The Mariners may or may not win a World Series in this poster's lifetime.
I can live (and die) with that.
