Good defense is never, ever,"fools gold".
There were some dumb turnover, but NO is one of the best defensive teams, and this is the 2nd time we threw that starting lineup out there. How about giving them a little time? You do realize this is what young teams go through, right?
When you say things like "If the improvement doesn't translate to more wins, it's fool's gold. Simple as that", I think your timeline of where you think he Kings are is way off, as well as your understanding of what a rebuild actually entails. If it's fools gold, then where do you think a winning record will come from? Answer, improvement.
Improvement over the next few years will lead to us being a relevant playoff team. Without improvement, which happens one step at a time, we'll never win. That is exactly why with a young, rebuilding team, you focus on improvement, and not recognizing it, or implying it's fools gold, is ignoring the very thing which will lead to the team getting those wins you so dearly want.
