Yes, those were some great teams in 1975, 1978, 1986, 2003 and 2008. In each of those years, the team caught some bad breaks that turned out to be good breaks for their opponents. In 1975, Jim Rice missed the entire post season with a broken wrist and then there was the the End Armbrister non- interference call. In 1978, there was the lucky catch by Lou Piniella on Remy's base hit to RF. He didn't see the ball at all and just threw out his glove. In 1986, there was the Buckner play and Clemen's blister that took him out of the game. In 2003, there was Grady Little and in 2008, there was Beckett's torn Lat. I would add 1967 to the list as the Red Sox had to face the Cardinals without Tony Conigliaro who was one of the brightest young stars in the game.
This reinforces my point that a lot of things need to go right to go all the way. Those were great teams, but the planets didn't align for them in those years. The same cannot be said of finishing last. You don't need a lot of bad breaks at critical times. You just need to suck and be a poorly constructed team.
