In fairness, I don't think Danny even thought the Nets would implode this much and that the picks would/could be this good.
Probably not to this degree, but it was obvious Pierce and KG would be either retired or extremely limited by the time the 2016-2018 window hit. And that's if they were even with the team. Add Johnson's inevitable decline and rolling the dice that Williams' dropoff would be sustained, plus no real up-and-coming players, and the knowledge that the cap structure would make it VERY difficult to add any more impact pieces, and it was a pretty good bet they wouldn't be #25-30 like a lot of people assumed when the deal went down.
Danny is consistently very good at playing the long game - realizing that in a league where few coaches and GMs are more than one bad year from being fired, a 1st 3-4 years out is easy to give away but may hold tremendous value when it actually pays off. We have a very slow-developing Memphis 1st that may turn out similarly, but it may take until 2020 or 2021 to see it. It's the classic strategy of finding overvalued and undervalued assets and exchanging the first for the second, and Danny plays it as well as anybody. The job security helps a LOT, though, and that's where ownership should be lauded as well.
