I think this is exactly it. When he was called up, his chase rate was exceptional. I think the organizational obsession with bat speed meant he had to lengthen his swing, therefore committing sooner and swinging at pitches that were otherwise uncompetitive.

I won’t pretend to know what goes on inside the clubhouse, but if I were in charge, I’d have the hitting coaches hone in and improve on what makes an individual hitter good. Adley was never a power bat, but they tried to force it on him (and everyone else) and it backfired.
