The '17 pick definitely has more value. Not only are the Nets currently sucking, but the pick would pay dividends sooner for any team that acquires it. I fully expect the Nets to be just as bad next year, but that is no guarantee. It is currently happening now, though. This draft is also considered 'loaded.'
As for Cousins, I am not sure that Danny is in a huge rush. He may want to see if he can get his hands on Griffin/Hayward for 'free' and keep his picks rather than paying a higher price now. Sac is faltering once again and they will likely continue to underperform. If Sac doesn't trade Cousins at the deadline, then his value will be even more diminished in the offseason (essentially an expiring contract) and Danny can revisit that option if Griffin/Hayward are not coming here.
Note, however, if Sac actively puts Cousins on the trading block at the deadline, Danny will have no choice but to try to make a move.
This is a bit off this topic, but I've often wondered how much poker is involved in trades. For instance, presumably, Danny has to make an initial offer, which is a bit lowball, something like Rozier, Amir, Smart, and the 18 pick. Then Vlade would say no, but he might counter with Rozier, Smart, Brown, Zeller and the 17 pick. To which Danny says no. But the point is unless Sac get a better offer then they just need to accept the original offer.
Now my question is, can Vlade bluff and say, "well Atlanta are offering Schroeder, Bazemore, Howard, and two first round picks". But let's say he is lying in this scenario. So is he "allowed" to lie about this? And does Danny has any means to somehow (through formal or informal channels) "check" whether Atlanta are indeed offering that much, and hence precipitate a willingness to "beat" their offer with a better package?
