The really elite ones are Moncada, Eloy, Robert and Giolito. Kopech could be depending how you feel (personally I think he may be the best of the bunch aside from Robert).
Anderson, Madrigal, Vaughn and Cease are a step below those guys. I would also include Reynaldo Lopez in that tier, as he actually showed a lot of things to be encouraged by this year.
Then you've got the quality players filling out the roster like Bummer, Colome, McCann, Abreu.
From what I see this just isn't good enough.
