  1. Awesome stuff, Jason. Now what about the other decades? j/k ;-)

    What's your IP minimum for each ten-year period?

    • 100 decisions and >75% starting appearances. Did that to filter the relievers

        Great, thanks.

    Maddux was great, but his is not the name that sticks out for "domination." Pedro dominated and by way of this graph was the better pitcher.

    100 decisions seems too few, doesn't it? I mean, Pedro had 0 GS in 1991, 1 in 1992, and 2 in 1993. Yet he holds the lead starting in 1991 (or however that should be phrased). Don't get me wrong, I think this is AWESOME and am a firm believer in anything-that-demonstrates-the-awesomeness-that-was-Pedro. But this does seem a bit off-kilter. I'm not sure what the fix is. But it does seem as if the decisions threshold was too low. What if we upped it to 200 decisions? That would mean averaging at least 20 a year or, more likely having 7 full seasons or 6 full seasons and a few partials in a decade. Otherwise, a guy could have a remarkable 4 years and be dubbed the leader of 6 or 7 decades, no?

    • It's funny BSK because on some of my other charts, I LOWERED the # of decisions to 75 so we can see where Lincecum (83 dec's) would fit.

      Toggling the filter open/closed certainly changes the view but does it add anything by doing so? I chose 100 because that would, in most cases, eliminate the relief-only pitchers.

      There's nothing exact about this process. It's what makes these sort of debates so much fun. I can change one of the variables and come up with new answers, and both would be right.

      The one thing that won't change is awesomeness. Pedro, Maddux, Clemens (as well as many others including Smoltz, Glavine, Schilling, Unit, etc.) all rise to the top. No matter how we slice it.

        Agreed. I suppose I took it more seriously than was necessary. The results just shocked me when I first saw them. Not that those three were so dominant, but that Pedro's length of dominance dwarfed the other two, but the primary knock on him has always been his endurance. No matter. Interesting stuff, regardless!
