Power and speed might score more than just power, or it might not. Speed doesn't guarantee more scoring. OBP guarantees more scoring. That is where the Cubs have been lacking. And you don't have to have great speed to get great OBP, but it's still nice to have. I'm saying that even if the power lineup scores more runs, and I concede that they probably will, the team with speed will still win more games. I think there are a couple of testable hypotheses here. Going back, I think the first hypothesis is that a speed team will score runs more consistently than a power team. We can compare the standard deviation of runs scored / game to test this hypothesis. The second hypothesis is independent of the speed issue, asserting that the a team with more consistent run production will win more games than a team with more variance in the distribution of runs scored. The second hypothesis is easy to test, the first requires a proxy for team speed.
