It's hard to see how the draft really cleared up any questions that already existed on the roster. At the same time, at least in theory three players were added to a roster that only has three free agents outgoing.
So yeah, I'm not sure the draft really gives flexibility. It doesn't really change much, though it definitely makes Evan Turner expendable. Smart, Rozier, and Brown should eat up his minutes. Should, I say, because I don't trust the team not to re-sign him, especially if other names in free agency go elsewhere. The team may be in a position to placate fans, and Evan Turner is a fan favorite, though one would assume giving the #3 pick a chance to earn playing time off the bench would please fans, as well.
