Here's something about 'randomness': it is a huge factor in baseball, and it does explain a lot of things. But sometimes it turns out to be the wrong explanation for something too. We've seen it happen a number of times that a pitcher has a rough outing or two, and at first you think it was just a randomness thing, but then they examine him and find out he's got an injury and probably had it in those bad outings. 'Randomness' is kind of a one-size-fits-all explanation that gets applied to everything.
