I've been saying this for awhile:
#16 + #33 + Olynyk for #6 makes too much sense. Toss in a future 2nd to sweeten it if needed.
They trade back and are able to get Grant or Payne with #16, establishing their PG of the future. They have Olynyk to be a legit stretch 4 next to Cousins, allowing him to do his thing down low. They get #33 which (imo) is more valuable than #28, because they are both close to the end of the first round, but #33 is unguaranteed.
We get #6, boom, WCS. We now have our defensive anchor of the future. We use #28 on bpa or trade up using #45 to get the best scorer available (RJ Hunter!!!). If we end up keeping #45 get a guy like Brown or Young.
Best Case Scenario:
6) WCS
28) RJ Hunter
45) Anthony Brown
