The olynyk and amir pairing has always made the most sense to me... even before we brought in Amir. I was a fan of bringing in a defensive big (ideally noel... but even someone like WCS or Biyombo had to be considered) paired next to Olynyk. We went for Amir... and it's cool to see them playing minutes together.
This spells doom for Sully's trade value, though. I felt like we were playing him early on to showcase him a bit. I still feel like he's going to be moved, though... can't imagine us giving him a big contract.
