Off the top of my head, Miami, New Orleans, Minnesota, Boston, Memphis, Cleveland, Atlanta, Milwaukee all have deep enough rosters to move players without immediately creating a void. And then you've got the teams like OKC, New York and such that have turned their bad seasons into stockpiled picks.
My point is that had we done our jobs well over the past several years, we'd have two or three more young role players or even stars in the making. Sure, we wouldn't have kept all of them but we should have retained some value from many of them instead of just wiping them off our books (sometimes using a draft pick to accompish that).
