Personally I'm starting to rather like the idea of signing Pau to a two year deal similar to Amir last year and then maybe signing or trading for another solid big who'd work next to him eg Zach Randolph or Nene.
Nene is terrible.
Pau Gasol with Amir and KO, A young big to grow and learn next to them from the 16 pick in this years draft. Johnson, Davis, Ellenson or Sabonis could work as PF bench players at that spot. If Zach Randolph would sign reasonable then grab him of course. Beware his age/health and temper expectations.
Use that number 3 on Murray, Hield, Dunn or even Brown if it cant be traded for a frontline star.
If we are desparate for a center then draft Poeltl or sign Dwight Howard. Both are mistakes IMO.
Point is if the right trade or FA players arent there then draft talent you can develop.
