Sorry I can only do so much. If anybody else feels they can take that on, I'm willing to help them but I suspect it would require going over, day by day, for every other team in the majors to see if they blew postseason chances.
I don't know how it's possible to do that.
What I do know is that the Sox keep giving away chances and it's biting them in the ass.
Honestly I don't need to know if the Mariners did it and if so how many times or the Blue Jays or the Orioles... because that doesn't impact the Sox financially and their fans does it?
To me, just because the Sox do it 'less' (for discussion purposes-- I have no idea if that's true...) doesn't mean it doesn't have a significant impact given the other related issues.
