UK, you note that Corey had flaws after AA that remain today, and that they were wrong to promote him when he had flaws. Some guys have non-correctible flaws. Most every prospect has some flaws, whether correctible or not. Is a team "rushing" a guy every time they promote a player with flaws? Obviously not, else hardly anybody would ever leave A-ball. Prior had flaws (slow delivery, poor at holding runners), but they promoted him anyway. Z had lots of flaws (wildness, obviously), but they promoted him anyway and he was slowly able to improve, regardless of level. When is it "rushing" to promote a guy with a flaw, and when is it perfectly appropriate to promote a guy despite flaws and figure he'll need to continue to work on them at the next level just like he'd need to at the current level? Corey has achieved varying levels of success despite his difficulty in reading pitches, which is his limiting flaw IMO. Would you have kept him at AA indefinitely? Perhaps to this very day, since he hasn't corrected it yet? (And has had not less but more motivation, if it were in fact a correctible problem...) No, teams do it all the time, where they'll promote a player prematurely despite flaws that will become more restrictive the further he advances. Corey's batting eye could be covered up in the lower levels of the minors much easier simply b/c he had a physical advantage over most pitchers having never faced someone with his physical gifts before. But, I don't the see the reason once you get past rookie-ball or short-season that a player should jump. If the Cubs feel a player is properly slotted at Low-A, are they saying they made a mistake by placing him too low in the system or he advanced quickly enough to skip High-A? We both know the jump from High-A to AA is a steep one within itself. I don't understand that reasoning, especially if you have a quality instructor in the system like Zisk who obviously has gained the respect of management simply b/c of the length of his tenure and various roles. I see nothing wrong with taking a more passive approach in terms of making it a priority to not rush a player. But developmentwise, there was a difference between Prior and Patterson, Prior was much more polished at West Tenn compared to Patterson. It's similar as to why I'd be upset if the Cubs had rushed Pie or skipped Daytona after Lansing. To me, it's an unnecc. risk to have a player skip a level, especially when they're as raw as Patterson.
