"Additionally the strength of a lineup can exaggerate the effects of a ballpark."
Uh, no, it can't. Unless you are arguing that there is some systematic fashion in which both home and away teams alter their lineups by ballpark to create that exaggeration. If there is such a study demonstrating that, I'd like to see it. It would be very interesting.
"Which brings on a fantasy paradigm: pitchers are becoming more predictable to forecast (therefore shouldn't be discounted as in the past),"
Uh, BS. His basis for stating this from the second article, was the following:
A: Does anyone remember early in the 2000s when famous Sabermetician Bill James wouldn't even do pitching projections because of his frustration with their predictability?
So, that's your first piece of evidence?
B.Don't get me wrong, they'll always be an increased injury factor as pitchers are just more injury prone (the "unnatural" pitching motion). Outside of the injury factor, I routinely correctly project an almost equal number of directional upswing/downswing among both hitters and pitchers.
In other words, ignoring the fact that pitchers get injured, I predict an equal number of risers and decliners. Any data to confirm that prediction, dude? Any effort to try to look at the size of those fluctuations, rather than just the direction, which is a critical element in predictability?
If you can't get the little things right, I'm very suspicious of that you'll get the rest of it right.
