What Ford (and some people in this thread) are missing is that this trade deadline is just the first of many decision points in the rebuilding process.
The question is not whether Danny could have gotten *something* for one of the Big Three. It's whether the options *now* beat what the options might be *later*.
As one example, even if maximizing cap space and getting high draft picks is the goal, it might end up being a good idea to keep Pierce now - because his contract will be far more tradeable next year, and could fetch a better asset in return. We'll still have plenty of space this summer.
Similarly, if we are able to re-sign KG for less (say $10m, one year), then he will be easier to trade next year as long as he's still productive.
It's not all or nothing, right now. And I think the outcome we got at this deadline (no deals) is pretty consistent with Danny's long-term vision. Danny understands that wasting cap space on mediocre talent and trading away valuable draft picks are what guarantee mediocrity. He did neither of those things.
Remember, he didn't build that first championship team overnight.
