Nets could also throw a ton of picks at them, but in the case of trading Young to a team that isn't SA they're more likely to value getting promising players as well, not just picks.
Young is a good player, despite his flaws, and there would definitely be a bidding war for him. Sure, Spurs can probably outbid everyone due to owning Atlanta's own picks, but he won't come cheap at all, both in terms of value SA would have to send and also salary-wise when they extend him.
