Re: AL Pitchers v. NL Pitchers
I've been trying to pull up Retrosheet to check out what they've got for Interleague game splits, but I've been having problems getting it to load. Off the top of my head, I'm not sure what all they've got for those splits. It'd be interesting to glance over, but I'm not sure how much more information we'd be able to learn from it.
With most league difficulty/era factors, I've just assumed there'd always likely be a small variance between the strength of the AL and NL in any given season. Prior to free agency, the variance would probably change slowly, perhaps generationally, but now with players moving all over the place it could be prone to changing much more quicker and perhaps on a season to season basis sometimes.
