For the most part, I approve of your assessment. I have seen many of these players in person, and will save time by not sharing my insight on each player.
I should point out one thing-Miguel Perez is a weak hitter, with very little power who strikes out a lot. In 400 at bats last year in AA, he hit just three homers and had a K/BB ratio of 88-19. In fact, he was just recently taken off the Reds 40 man roster, a smart move.
Based on my personal observation over the years of him...defensively, he's sound. In fact, he's very good. Right now..he can't hit. Maybe that will change.
But there are a lot of Reds front office people that are privately saying this guy will never be an every day starter. And I would be very surprised if he is in the Opening Day lineup next year.
Peace to all as we'll continue to cover the area for you...
