No. Those are the type of overpayed players you want to avoid in the trades as well, but couldn't.
Cap flexibility is for more then just signing FA.
What is it for then? 
Is this sarcasm?
You can use cap space to trade for players.
Memphis is probably the biggest recent example, they traded for Zach Randolph with their cap space and the Jazz did something similar to get Big Al (used a trade exception but cap space works for that too). Another example would be OKC picking up Eric Maynor in a salary dump from the Jazz.
You can also use cap space to take on salary and pick up cash/picks for your trouble.
You are right, I did not see that. But if you can trade RA for a young talent / pick and a bad contract, why not? C's will have the space to do that while rebuilding in the next years.
DA has played his cards perfectly: he has lots of contracts, all of differents sizes and all nearing their end. So I would not be surprised to see him taking a bad contract if he can get some value to go alongside.
Anyway, it's gonna be the plan. Draft, minor moves, accumulating talent and see what happens.
Now, I'd rather see thoses moves starting to happen now rather than next year. If we can get good value now, let's do it, even if it means that the franchise has to take a 2 or 3-years bad deals in return.
