Getting back to 2009, going to baseball-reference and Wikipedia and seeing how many teams went back the WS the year after winning it...the success rate for teams not named the Yankees trying to pull off the WS repeat is mediocre at best. Eighteen teams not named the Yankees have gone back to the World Series the year after winning it and only nine of them have won that second consecutive title. And only one in the last forty-six years (the '93 Blue Jays). The Yankees, however, are 12-4 in repeat attempts. I guess the moral of the story is that unless you're the Yankees, the climb back to the mountaintop is just as hard as the first climb up to it.
WIth the caveat that this WS has yet to be played, this feels like a little bit of both 1993 and 2009. The fight, spirit, camaradrie and the hunger of these guys and the sense of playing with house money reminds me of 1993 while facing a clearly-superior-on-paper opponent reminds me of 2009.
