If the Suns would accept the discussed options(Poirier or Ojeleye) and a pick, then I think you need to make that trade, it's tremendous value and I think, as others, Saric would fit in well.
Now, that said, the more I watch Grant Williams, the more I like him and since he has really been balling over the last month, would hate to do something that reduces his minutes to continue his development. So if Danny passes on Saric because he wants Williams to continue to get minutes and play better and better, I can respect that.
