...before giving up on one "blueprint" and starting over with a new coach, trading away key players and perhaps making changes in the front office?
This came to mind when the issue of competing now and sacrificing the future or building up to competing down the road came up again in another thread. Assuming a team can build to the point where they're making Conference Finals appearances or at least getting out of the first round every year but never winning it all, how long should they stay the course before going for broke and making a major change to try and get over the hump? Should they just ride their stars until they ride into the sunset and the inevitable rebuilding phase officially begins? Could you really put a standard length of time on it, or is it simply a case-by-case matter?
On the other hand, you may have a team that's lurking in the basement and never seeming to get ahead. How much rope should general managers, coaches and players be given before it's decided that the current plan isn't going anywhere and it's time to blow up the roster, get a new coach and find someone new to call the shots when it comes to basketball operations? And again, what conditions could you place on that length of time and should some teams stick it out longer than others?
For a team that is winning but isn't getting over the proverbial hump, I think they have to be getting closer and closer to the goal each year and have come very close a couple of years running, say losing in six or seven in the Conference Finals. So long as there's that continued improvement, I'd say four or five years of progress and near-misses before pulling the trigger on a major change, either a new coach or one of the key players in the rotation. If no real progress is being made, perhaps only three years before making a change; not necessarily blowing the team up, but I think three years is about as long as an above average team should go without getting any closer to the ultimate goal.
For an unsuccesful team, I would again say four or five years, depending on the blunders being made. Obviously if the decisions were really poor or there was a real problem with a player or coach then changes might come quicker, but barring a situation like the Celtics' 2007 offseason, there's not going to be a turnaround in the space of one season. In the normal case, five seasons should be enough for a basement team to draft a couple of players and work some other magic in terms of trades and free agent signings. If there's no progress by that point, it's time for changes to be made. Not necessarily wholesale changes with the roster but perhaps a coaching change and certainly someone new in the front office with a different plan moving forward.
