This is hinted at by your constant touting of the success of your other statistical probability models. If that's not the case, then those probability results are irrelevant and don't add any value to your claim for Koufax anyway. 2 ) You constantly ignore other intangible items that, while oft times not quantifiable, are still non-zero. This is demonstrated, in part, by claims such as athletes are better today than they were years ago. While true, you continue to ignore the fact that athletes years ago played and trained under different conditions with what was available at the time. You're implying that had those 'lesser athletes' been born and raised in today's environment, they would not have taken advantage of today's methods and still been throwing rocks at a chalk outline on a barn. Maybe try the reverse? Put Koufax back into the 1930s environment and do the analysis and you'll have different variables to consider. It is possible he wouldn't have made it out of the Dodgers or Cardinals 13 or so minor league teams.

Taylor, Great points, and part of what I've been saying all along.
