I'm not sure why add CJ Miles to the deal? Does it change anything?
Now, talking of trading PG, it all depends on how good that nr 2 pick will be. Based on what I've read, yep, I would do that deal (nr2 pick plus two players).
Or nr1 pick plus Bradley and the Dallas pick. The reason is that PG is on a reasonable contract for three more seasons.
But again, I'm not a draft specialist: this is a very delicate question: imagine making the trade and Ingram turning out to be the new Durant
Also keep in mind that I doubt Larry trades PG. Everything he has said and done so far points to the direction he will keep PG for as long as he can.
