I think that there may be a way to realistically implement catcher's game-calling abilities in historical league simulations. Perhaps you could look at a catcher's offensive and defensive statistics and compare this to the percentage of their team's games that they played. For instance, a catcher that played a high percentage of games, but had poor offensive and defensive stats might be in the game because of his ability to handle pitchers or call the game. (For our discussion here, I'm equating ability to handle pitchers and call a game to be statistically the same.) This catcher would slightly raise a pitcher's stats. Similarly, a catcher with good offensive or defensive stats that played relatively little, would slightly decrease a pitcher's stats. After all, if some catchers are exceptional and raise pitcher's stats, there must be catchers that lower their stats. Other catchers (that seem to play as much or as little as their offensive and defensive abilities dictate) would be assigned game-calling abilities randomly, with no effect being the most common.

SInce you normally play good players more often; the bad catchers would hvet to outnumber the good catchers to insure historical accuracy.
