I know the Marlins keep a big majority of their prospects in Double-A and call them up straight from there and have very few big prospects in Triple-A. Hardly ever does a "prospect' with the Marlins go to Triple-A before being called up, it's usually once you're in Double-A, you're almost ready. Does that help?
This pretty much how I see it, and a friend who spent 3 years in various levels of the Minors elsewhere described his experience similarly. He says guys who are successful at AA got what it takes talent-wise, then it's all about opportunity, and having your head in the right place.
