From 1980 -1985, there was only one sub .500 season, and there was quite a bit of excitement and competitiveness in some of those seasons so I would not term that period as futility. That is a misrepresentation by you. The years of Crackhead Hobson 92-94 were pretty bad, and I was happy that the '94 season got canceled.
Where were you living that you had to tolerate Yankee fans? I was living in Brooklyn, NY until 1989 and then Long Island, NY so I am familiar with living with Yankee fans. Finishing last with no hope by the All Star break is the worst for me. I can understand 2013 washing away 2012, but how does it wash away 2014 and 2015? I don't get that. Maybe you give them one year of grace after winning a championship, but 2 years of last place. I am sorry, but last place was starting to feel like a permanent dwelling place. It was awful.
