OK, it's a stretch to think the Red Sox are likely contenders for another World Championship in 2015. But they could well contend. Stranger things have happened.
And I haven't given up on this season yet. I wouldn't do that until they are mathematically eliminated. I think most of us recall great finishes such as the Rockies had in 2007, when they were 15-1 from September 16 on. They were in fourth place when their streak began.
(Then they swept the NLDS and the NLCS - only to run into the Red Sox, and get swept by Boston.)
That aside, it's kind of interesting to notice the Red Sox pattern of ups and downs in recent years - If the Sox fail to make the postseason this year, it will be five times in 11 years they have failed to do so:
2006, 2010, 2011, 2012, and 2014
But they won the World Series three times (and I don't even need to write out the years - everyone reading this post can recite them from recent memory.)
