Isn't a "good" trade, given teams with different needs, one that brings in more value than you send out and does the same for your partner? If you only meet your own needs and not the partner's, you won't make many trades. In this case the Celtics and Spurs are in very different places. If you believe the C's are a 3rd star and a couple upgrades away from contention, the White deal (and Theis deal) moved them a step closer. Brad now has assets with tradable salaries to upgrade from White, Smart, Horford, maybe Rob to a legit 3rd star. Trade Smart a week ago and we'd have a new hole to fill. Trade Smart or White now and there is no new hole. C's now may have assets/contracts to compete with other teams for a star -- Lillard (as an example) perhaps? Bump up your assets and flexibility incrementally with each move and eventually you can get what you need. Otherwise, pray for a miracle draft steal, an Ainge-type "win" from a naive GM, a player who insists on being traded to the C's, something to fall from the sky onto your lap -- who do we think the C's are, the Lakers?
