Obviously too many unknowns right now. However, if we pick a 4/5 and Giles is anywhere as good as advertised, we must seriously think of trading Willie.
I like Willie, and think he will be a good player in the league for years to come. However, given that we will have two potential cornerstones in Giles and pick, with Skal and Papa to back them up (with Z Bo and KK still possibly around), Willie will not have the same value for us. Among all the players we can and might be willing to trade, I think he will have the highest value. We still have a big hole at 3, which we will need to address, and a trade with Willie as the chief sweetener might help there.
Of course, if we draft a 3, this discussion becomes irrelevant. In the former scenario though, we should try and make a serious run at Paul George. While he might prefer staying in OKC, or potentially move to Lakers, if we can sell him on a future of playing with Fox, Giles, a high pick, Bogdan, Buddy, Skal, he might be tempted. We do have pieces that can grow and compete for a long time. We need to stop screwing up, and give hopes to potential tier 1 free agents that we can field a winning team. A little success will hopefully beget more success.
