JP Ricciardi's "analytics" drafting philosophy did irreparable damage to the farm during his tenure. In the early 2000s, the SABR community didn't recognize the importance of the hit tool and decided that high school pitchers had no value (Billy Beane famously threw a chair at his development team for drafting Jeremy Bonderman and traded him immediately).
Before and after Ricciardi Toronto had one of the most respected development systems in baseball.
