Randomness in baseball or life in general is very small. There is always a small bit of chance it won't happen, but pitchers who walk batters consistently have high ERAs and airplanes don't fall out of the sky for no reason at all. Numbers show patterns and trends. To base baseball decision on hunches, feels, and guts is not the way to win. As with most things, there is truth on both sides of this issue. High OBP is always good, but it's better if most of the time it's in the context of a team rally, which is of itself random. Get more high-OBP guys on the same team, there is less randomness. Quality starts usually correlate closely with wins, but it's the randomness of when you throw them that makes a huge difference in W-L results. Compare Zambrano or Sean Marshall with Jason Marquis. That's not ture at all. Randomness is chance or luck. Over the course of 160 games luck plays a very limted role in who makes the playoffs and who doesn't. Randomness is a convient excuse for why things don't happen the way we want them too. The Cubs aren't bad becuase the gods hate them or because of chance, they're bad becuase their numbers indicate it is so. And using wins as a metric for starting pitchers becme usless around the time of Rolly Fingers.
