The reason why I chose it as a stat is -- you have to choose something. And it seemed relevant to my question. A quality start means the guy pitched far enough into the game to get to your short relief men, and when he left, your team was still in the game. And I know there's not much difference between a 1 and a 2 -- you should probably expect some consistency of quality from your top 2 guys. But there's presumably a difference between a 1/2 and a 4/5. So when you say, as everyone does, "We need more pitching," how does the more pitching you're likely to get compare with the pitching you have? If an Alay Soler, for example, gives you one quality start out of every three outings (just picking numbers out of thin air), should you figure that this is way below average, and that you can reasonably expect to go out and find a bottom-of-the-rotation guy who'll give you two out of five? And how much is it worth to you to give up, in order to boost the bottom of your rotation from 33% efficiency to 40% efficiency?
