Smitty- The issue with small sample sizes has to do with the predictability of the results within the sample. A streak is just that - a small sample with no predictive value. Sure, streaks exist and players feel hot and cold. No doubt about it. But it's impossible to predict when those hot and cold streaks will start and/or end. Your Josh Hamilton example is a perfect one to illustrate the volatility and arbitrary nature of streak lengths. Relying on unpredictable data for measurement of future actions, in and of itself, is bad decision making.
