What are you talking about? You could point to hundreds of Minor Leaguers who had great numbers in AA or AAA and didn't do anything in the Pros.
Peacock or anyone else is no different. Scouts are not deriding his stuff. Guys like Kevin Goldstein just said a few days ago that he has two true plus pitches (fastball, slider). Goldstein says he is a big fan. Others will soon hop on board. One or two jerks started the rumor that he had a flat fastball that will get battered and people carried that like it's gospel.
Peacock could be a stud #2-3 pitcher or he could be a back end starter or maybe even a late reliever. That has yet to be determined. But to compare him with Sonnanstine and Slowey make no sense. Why not compare him to a pitcher with similar numbers that is a stud? To make any comparison is not fair.
Let's let his pitching dictate everything. As long as he keeps dominating and striking guys out his future will be very bright.
