Re: Have you ever noticed that....
It's not really a discussion worth having. There are rarely ever enough true prospects in a system to fill out a minor league rotation. Right now, the only legitimate SP prospects that the Reds have ready for the AAA level are Cingrani and Corcino. Most organizations are in a very similar situation.
Also, the major league club almost always needs SP depth. Most teams use 8-10 different starters over the course of a season. It's definitely a good thing to have a couple of guys stashed at AAA who are known quantities and have some MLB experience.
