What I don't get about your irritation is that all we are asking for in the immediate future is for the team to be "not downright terrible."
So, yes, some of us are ready to be "done being bad." Personally, I'm looking forward to mediocrity--at least in the short term.
I can understand where you're coming from on that. I guess, for me, there's just not that much difference between being mediocre and being bad. The mediocre team plays well enough that you don't face palm quite so often as you try to watch them. In the big scheme of things, they're still not relevant to the rest of the league and exist as a doormat for contenders.
My position, which I've said many times around here, is that what matters most to me is having a core group in place that I feel represents some kind of framework for future success. In that sense, how "good" the team is in the short term is less important.
I'd rather watch a "bad" team that had a collection of really promising young guys who could plausibly coalesce into a competitive core than a mediocre collection of "assets" that will probably be shuffled around 5-10 times before we get to watch a team that's actually honest-to-goodness competitive.
In brief, I look at the current Celtics and I see maybe
one player who I think stands a good chance of being here in four or five years. That was fine when the team was looking to compete for a title each year. Now that they're floundering in the middle, it bothers me a lot more than the team losing more games than they win.
