I provided records and standings as evidence to my position. I lived and breathed every moment of those 3 last decades of the century. That has nothing to do with stats and standings. I never understand how some people think people who enjoy stats are blinded by them and can't relate to the love of the game at the same level as those who don't. I played baseball for over 20 years. It's in my blood. I used to dream about playing, often. I never dream of stats.
There was a lot of fun and excitement. Even when we did poorly, which was about half the time, during the last 2 decades, we had something or someone to watch and enjoy. As many times that I felt heartbreak and frustration, it was still fun watching the Sox.
That being said, there was always an underlying feeling with many fans I knew that our management/ownership team were either bozos or people who would not invest just enough to get us over the top and win a ring. There was no sense that management was trying to build a "sustainably" highly competitive team. Instead, we felt like they were doing just enough to keep us interested and hopeful, most springs and early summers.
Don't get me wrong, they built some very competitive teams from 1970 to 1999. Good enough to win it all, with a little luck, perhaps. My point was, I never felt their goal was sustainability, and that is the only word I am focusing on for those decades.
I do think the FO tried to give the fans some great players to follow. Except for the purges in the 70's, most of our best players played until retirement or late in their careers. I appreciated that.
The teams of the 2000's and 2010's did not do that, but we won 4 rings and finished in first or second place more often that the teams of the 80's and 90's. Both 2 decade periods saw 6 last or 5th or lower place finishes.
As much as I loved watching the Sox for those last 3 decades of the last century, I enjoyed the last 2 decades more. These last 3-5 years have been difficult, but there were difficult stretches back then, too.
As for not understanding the WORD, you wrote...
Boston fans never even heard the phrase "sustained" contenders in the final decades of last century, since it was a given the Sox already were...
I'm disagreeing. We were non contenders as often as contenders. Being an optimistic Sox fan, I do remember feeling we "had a chance" more often than not, most springs, but deep down, I knew we were longshots more often than not, those last 2 decades. Interestingly, I like our team in '87, for obvious reasons. I had strong hopes, that spring.
Many, many springs, I did not have realistic hopes.
