Castle/Dillingham is my best outcome. In fact, the only outcome I really like. Probably can sub in Reed if I had to.
I'm not sure about Clingan at two. I don't think Washington gets a Jakob Poeltl type that high and their fanbase doesn't either. They seem to expect Topic or Castle.
I think there's real risk for Washington, Houston, Detroit, or even Charlotte taking Dillingham. If you spread out all the players and ignore mocks, just genuinely look at what you have, I think Sarr, Reed, and Dillingham will be around top three on some of these boards.
That said, it's very uncertain. It's more likely two and three go like Topic, Reed or Risacher. But I'm with those who say don't leave the rest to chance. Take Rob at four. If you at scared Castle is gone before eight, look into the type of trade the Pacers made last year and throw some seconds at Charlotte to see if they'll move.
