The point of the discussion, to me, is people such as yourself, clamoring for a PS QB, when, in fact, the PS is there for a team to develop players of potential.
Teams don't need PS QBs if they don't have one worth stashing away. (and that's the point of this discussion)
Reading more closely you haven't clamored for a PS QB so apologies for my confusion.
What you're wrong about is the fact that few positions are covered by the PS.
