At the very least, there's some very intriguing arms in the minors this regime has drafted/signed that have seen significant upticks in velocity and stuff. Ricky Tiedemann, Hayden Juenger, Yosver Zulueta, Trent Palmer etc. It's possible it's taken this long to overhaul pitching development and we're just now starting to see the effects percolate in the minors. I know that the pitching lab in the Player Development Complex didn't get going until the middle of last year.
What hurts is that none of Anthony Kay, Trent Thornton, Thomas Hatch, Julian Merryweather, Nate Pearson, Ryan Borucki, even TJ Zeuch considering he was a 1st round pick have contributed this season in any meaningful way. Some of those guys seemingly have ability and fell apart due to injury (Merryweather and Pearson), but most just outright don't look like major league pitchers due to a skills deficiency. Some were acquisitions from other teams (Hatch, Kay, Thornton), so maybe it's just a matter of scouting and analytics vastly overestimating their ability and misevaluating them? Then again, Hatch and Thornton weren't traded for superstars. Did we end up putting too much faith in fringey pitchers that the Jays hoped would break out and just haven't? Is this just us getting unlucky to some extent since pitching development is kind of a crapshoot?
So many questions, and the truth is probably a little bit of everything combined.
