You can be disappointed in the outcome, but that doesn't classify the team as a disappointment. Those are entirely unfair and unrealistic expectations. It's ok to have them as a fan, but they don't define the team. For each person? Sure it does; it's a relative a disappointment. Nobody is saying, "the team sucked," but relative to my hopes/expectations as to how the season would go I was disappointed. The first half was frustrating and the playoffs mostly were not enjoyable to me, especially (obviously) with how it ended. Again, doesn't mean anyone is saying they were a bad team, so don't worry. As pointed out, it's awesome that THIS is the kind of thing people can be disappointed over.
