I wasn't going to dare trying to include all 100-plus years of A's history in this article—so I chose to just focus on the Oakland years.
Ranking these moments was out of the question, too, so I just listed them chronologically. Older A's fans who lived through the 1970s World Series runs, please correct me if I missed any significant moments there.
This is my third and final "evergreen" assignment from bleacherreport.com as part of an agreement in becoming a featured columnist. I'm glad to have these assignments behind me so I can continue writing the articles I want to write. Enjoy.
