Richardson & McDermott for Westbrook + an unprotected pick seems ok. But why add Tre & Zach? I'd say chances are not high that you can get a better player than Tre even with a better 2nd rounder than what was used for him (#41 I believe). I'd expect him to command ideally a couple good 2nds, at the very least one. As for Zach, he's on a cheap contract with low guaranteed money, he's a useful guy for some team. You don't need to put together a winning team for the young core to develop, but you can't rid yourself of every single guy with some experience, and they're not costing us lottery odds, so why get rid of them? It's a total tear down, I'm not totally opposed on paper if the price is too good, but I'm not sold this is the case here.
