You could do better distributing your talent, then. If I were in your position, I'd more or less give up on blocks and rebounds. You should be able to get good value for Chandler. Maybe somebody like Okur would do well enough for you at Center along with Sheed, but guard stats are expensive with centers.
Yeah, you're in good shape with 3s, points, steals, but the rest of it is looking pretty rough-and-tumble.
