also apart from the iggy acquisition, they have been frugal about giving up picks. they drafted three of these guys and didn't give up picks for KD. if they keep drafting well they can handle the loss of one of their big four. i believe klay is the first up for a monster contract after the 18-19 season. i would imagine he will not re-up barring some willingness to sign for less (and durant also being willing to do the same, and more than the marginal discount he's bandied about recently).
