A) I have already presented several times that the strike zone used to gather data on the umpires gives them a leeway zone about the size of the baseball itself. That argument is incorrect.
B ) It uses the myriad cameras used to gather the data itself in order to adjust the strike zone to batter height, and stance. In 3d. In real time. This argument does not fly.
c) So what? Baseball did not have a DH, instant replay, or divisional/championship rounds for 100 years. All of those have changed the game for the better while actually changing fundamental parts of the game, which is your argument. Helping umpires enforce a strike as defined by the game's rulebook is, by definition, defending a fundamental part of the game.
