Candelario would be a top 10 prospect in the majority of systems in baseball. Probably the 9th or 10th prospect in the better ones, but he's still a legit guy. Zagunis probably makes plenty of top 10 lists as well, just due to his proximity to the majors. Many lists will throw a guy like him in at #10. Wilson and Albertos aren't making many lists though. As others have mentioned, this kind of thing happens when you graduate loads of talent to the big league team the past 2 years, and then deal from the remainder of the farm to bolster those graduates for a WS run. Candelario has like a .600 OPS when the temperature is below 80 degrees. He's a perfectly fine prospect and would make more than a few Top 10s, but it's also telling that all the Candelario conversation from Cubs fans(who are going to overrate him the most) is "what can we get for Candelario" and not "how can we fit Candelario in the roster/lineup". But he's easily the best of that list of 4, it's more that he's in the Top 10 and those other guys are too. Zagunis is next-gen Matt Szczur. That's fine and the system needs to provide those guys for injury depth and cost efficient bench/platoon players, but in no good system should he be ranked #6.
