I disagree. Assets are incredibly important in a rebuild. OKC didn't get to the top by building from scratch, they got to the top by controlling some ridiculous percentage of all draft picks for like a decade and by getting a future MVP in trade.
Yes, a bunch of dudes on our roster aren't part of the future. But we don't need cap space. As Sacramento, we won't be signing any significant free agents until we're compete-ready, you can book that. So there's no real penalty to letting contracts like LaVine's just expire if we can't trade them for positive value.
There's this zeitgeist of impatience around here that holds something like the view that if Nique doesn't play 30 MPG starting right now that we're blowing the rebuild, or that not giving Carter any run in his second year will bury us, and I think it's silly. Nique isn't even ready for 30 MPG. Let him move from the shallow end to the deep end at his own pace, don't just throw him in and hope he doesn't drown. There's obviously some reason that Carter has been buried on the depth chart thus far, and we've still got two and a half years of control of him to figure out what he can do.
There's just no hurry. There should be no difficulty in trading DDR for positive assets by the deadline. We can almost certainly get something for Westbrook (if we even want off of him - yes, he dominates the ball, but I'm pretty convinced that he teaches the kids the right attitude and effort by example, so for that alone he's probably worth keeping). Monk should have value, too. Maybe even Schröder can be flipped for less than nothing. And while I remain an advocate of keeping Domas and trying to incorporate him in whatever we're doing, if we choose to deal him we should get a truckload back. Now, we may not be able to (or want to) trade all of these guys, but we should be able to trade some of them, and with the exception of Schröder none of them has a chance to be a burden on us beyond next year (and we can get out of that for about $4M).
TL;DR: Patience and assets is a lot better than impatience and an empty cupboard.
