Let me walk back my earlier post a bit - I did a poor job and rushed out the post without looking up a thing or two and that's always a bad idea. I agree with most of the sentiments here - if I could get KD and Cousins for the picks, yes, I'd do it (basically Cousins for the picks and KD as a FA). I get that. I lost track of how young Cousins is and while his games played the last 2 years - 59, 65 respectively - are a concern, he's a great young player about to enter his prime.
Years ago here there was a lot of back and forth here on how the C's should treat their assets pre-KG and RA. One example was several people wanted to trade Al Jefferson, etc. for Allen Iverson to get Pierce a running mate. This wasn't hard to argue against and I and several posters did, making the argument that the assets had value and you continue to develop them until you get the right player to pull the trigger on and AI wasn't it. Obviously, KG was the right player - even though he was 3 years older compared to KD - and one knew it was going to be a pretty short window (and it was). That was fine though because the quality of the C's assets wasn't that great - 5th pick of the draft, Al Jefferson, etc.
This time around the value of the C's assets - or at least the potential value of those assets - is much higher. Yes, we have the 3rd pick in a 2 player draft, but it's still a very high pick and the team should at the least get a good player from either the draft or in trade. The next 2 Nets picks are gambles, of course, but they're high risk, high reward - and it's very rare for a playoff team to be in a position to enter the draft with the chance to add an elite talent free of charge, let alone 3 times.
Like KG, KD is a player you spend those assets on, but I'd only do it if the complementary player can also anchor a fairly long run. I'm hoping to watch a team that'll be really good for a generation and this franchise has a unique opportunity to perhaps draft their way there. I'd be very very conservative with those picks and the player/players I'd spend them on. And I wouldn't be surprised if Stevens' extension signals that Danny is fully prepared to wait it out.
