Dodgers player development is cutting edge. I remember there was a Baseball-America article that highlighted how they have some of the best facilities, coaching, more nutritious foods/spreads, specialized development plans, and resources available to players throughout the organization. But they also basically train them to be major leaguers from the start. They relay information/scouting reports in the same format to minor leaguers that they do to the major leaguers, which makes it almost a seamless transition for some of these guys from the minors to the majors. That's why you see guys like Bellinger, May, Gonsolin, Smith come up and basically start raking right away.
Jays have also been implementing some of the same things the Dodgers have been doing the last couple seasons, and we're just now seeing the fruits of it. It's why I had the utmost confidence in what Shapiro/Atkins have been doing, basically since they first got here.
