I absolutely wouldn't mind an alternative system to calling balls and strikes because that's the single most varied human aspect of the game. zones often change dramatically from day to day, inning to inning, and batter to batter. that said, the relative infrequency with which bad calls are made on routine plays doesn't leave me clamoring for a computer to decide a close play. I'm sure studies would show the correct call is made by an overwhelming majority. bad calls tend to even out over the course of a game and season. I do agree that something should be done about the umpires who act as though they're bigger than the game. the ump who is quick to remove his mask and follow a hitter to the dugout is an unwelcome part of the game. the same could also be said about the players who act in the same manner. the art of civil disagreement has been lost in the Robby Alomars, Milton Bradleys, Delmon Youngs et al of the world. both sides are quick to escalate, and it's one facet of the game I would like to see addressed by the unions.
