I don't understand what you are getting at here. Small sample size fluctuations are not the same as randomness. If we get swept in Detroit, it might mean nothing. If we get swept every single time we play Detroit, over and over and over again, then something is going on. Grab a coin and start flipping. See how hard it is to get only heads to come up, over and over and over again. It won't happen. Technically it could happen, but you probably won't live long enough to see it. For the Twins to get swept out of the first round, year after year after year, something was going on. If it was pure randomness, they would have won approximately half of the first round series, then roughly half of the second round series, etc.
