Here's an idea worth considering. Trade our number 5 pick to Houston for their number 14 and number 16 picks. As a bonus, try to get the Rockets to also take Garcia or Salmons.
Why do this trade? From reading various mock drafts, one likely scenario is that the number 5 pick would come down to Beal or Drummond. Neither is a particularly good fir for us. By trading down, there are many possibilities. At number 14: Zeller, Henson, Leonard, Moultrie or even the long shot a Sullinger if he slides. At number 16: Terrence Jones, Quincy Miller, Ross, or Harkless.
If ,on the other hand, Barnes, MKG, or Thomas fall to #5, don't do the trade.
