You are making my point. I have no obligation to support this team. It is my choice. It is everyone's choice. Good management is the expectation. Winning is the expectation. A Stanley Cup, no, that cannot be the expectation simply because you cannot control what other teams do, too many variables to "expect" that. But to compete for one, most certainly.
So again, I am not sure why I am "lucky" to root for this team. This team is the expectation, not the exception, not some luck of the Irish, or unicorn. And the team is not playing like they are capable. When they win, we celebrate them at epic levels. When they lose, if it is due to being outworked/outplayed, we are all over them with the same fury.
That's how it works here in Boston, and if you look around, many other very successful sport cities.
