Seriously? I guess they've probably drafted pitching well, how much of this is a product of simply taking lots of pitchers I don't know, but I don't really think there's much evidence for this regime being any good at "developing" arms. We've seen a lot of guys scuffle at various levels (Labourt, Tirado, Sanchez, Smoral, Norris) including the big leagues (Hutchison, Boyd, Castro, Sanchez, Norris). Essentially everyone but Stroman and Osuna could be better, or could have been better here. We've also seen several guys leave the organization and seemingly improve (Henderson, Syndergaard, DeSclafani, Sam Dyson, Graveman?).
Basically, if the Blue Jays were actually any good at "developing" pitching, then they'd have better pitching right now.
