At the end of it all, this is exactly how I feel.
For the most part, I haven't ever expected the Spurs to win a le (though, obviously, as playoff runs have developed, the sense that they could or should win the le has evolved). But to the extent that expecting a le amounts to a belief that they should compete for a le, I haven't actually "expected" a le since the beginning of the 2006 playoffs. Everything since then has been a bonus to me.
I was thinking about this earlier: there are fans of some franchises who would be ecstatic for their team to make, say, consecutive appearances in the 2nd Round or to reach a (1) conference final; an (1) NBA le is largely unthinkable for those fans.
My team has won 50 games or the equivalent for 14 straight years. My team has reached at least the 2nd round in 13 of the last 16 playoff seasons (and 15 of the last 21), played in 7 conference finals in those 16 seasons, reached the NBA Finals 4 times and, obviously, won all of those. Seriously? 50 wins is an expectation? A first round loss is a disappointment? Almost half of the last seasons over the last decade and a half have resulted in runs to at least the Conference Finals? Really?
Had you told me in 1991 that the next 20 years would bring that kind of success, I would have taken it in a heartbeat, no questions asked.
Are there other franchises that have more storied histories? Of course. Does that mean I don't enjoy and appreciate what my beloved, small market team has accomplished? Absolutely not.
Because of that, there really isn't much about the Spurs that concerns me any more. I'm a passionate fan; I hope they win every game and I'm hopeful that they can find a way to win another le, no matter the problems that may seem to exist. But if they don't? meh.
