Let's narrow it down. Every remotely available decent shooter with at least ~4.5 attempts per game. Which are available for Zo or Zo/Bled or Zo/Bled/Redick/picks and play defense and aren't old and would be cheaper than Zo? Not as easy at it might seem to hit that criteria. (pardon the eye-bleed format)
