That would be stupid.
Outside of Embiid, Wiggins, Parker, Randle, Exum and Smart this draft isnt all that special. Sure there is solid specs like Hood, Lavine, Gordon or Vonleh but I'm not convinced any of them will turn out better then DeMar eventually will (I dont think hes maxed out quite yet).
Unless we get one of the top 5-6, trading DeMar for any other pick would most likely be a backwards move and that isnt even lncluding the fact you want to add another pick.
