@APBABASEBALLFAN Fridge is correct. The year matters.
Let’s compare two pitchers from the GTOP sets: One from a good hitter’s season (the 1930 Cardinals, GTOP-4), and one from a good pitcher’s season (1968 Tigers, GTOP-2).
Over approx the same number of innings pitched, Sy Johnson (Cardinals) had an ERA of 4.65, while Joe Sparma (Tigers) had an ERA of 3.70. Sparma’s ERA was significantly better. Yet, both are rated C’s. In fact, Johnson is a much more attractive C-YZ than Sparma’s C-W.
Some will argue that’s why they don’t like to pit teams from different era’s. And they’ve got a point, I suppose. Personally, the beauty of APBA is being able to play teams from 1930 & '68 against each other… and enjoy it for what it is.
