Obviously the Kings would want the Nets' pick. It might actually come down to that. But given how messed up things are with the Kings, I think we'd all like to see Danny take advantage of that situation and not give in on that.
That said, for all the drama, Cousins is a pretty amazing player and I'd be willing to give up pretty much anyone and everything but Smart and the 2016 Nets pick to get him. I'd be willing to give up the Dallas pick, later Nets picks, and pretty much anyone else on the team.
