You mean an utter disaster based on the result, or the expectations?. Because if it was based on the result, then I agree partially. The yanks are supposed to go to the postseason every year, and the year they don't should be a "disaster". But in the other hand, we are so spoiled as a yankee fans that we "expect" them to have a shot at a championship every year, and that's unrealistic.
I disagree if that was based on the expectations. 2008 was the year when all the bad decisions of the previous years finally hurt us. Also we had some key injuries (Wang, Joba, Posada) that were devastated. And anyway, before all that, since the beginning I didn't saw the yanks going to the posteason, because Boston and Tampa were better teams.
This year it will be dissapointing in every way, but as I said in my "little boy" post, being the best during the regular season can assure you nothing. At the end, a little thing can change the outcome of the whole series.
...and I will drive my post count up, so I can be treated as a "big boy", as I can see
