I suppose that will depend upon the development of the players we have. If they come along quickly, they may be viewed as a sufficient set of complementary players. Off the top of my head, the most likely players to be attractive as teammates are (in order of appeal)
1. Smart
2. Sullinger
3. Bradley
[3. Bass, if he's still around which I doubt will happen]
4. Crowder
5. Turner
6. Zeller
After that, not much. Young, maybe as a wild card. Maybe if two free agents were wooed at the same time, they would view the whole picture (including the $$, the coach and the prospect of improvement will all the draft picks in the hopper) as sufficiently attractive. But I feel like I am whistling past the graveyard on this.
