As MLB’s General Managers fail to reach a consensus on the matter of instant replay, let’s consider for a minute whether or not such a practice is necessary or even preferable. Left to the power of human judgement, the umpiring crew in the recently concluded ALCS went to great lengths to get it right. Though there’s no shortage of days & nights when the strike zone seems to vary wildly, there’s been no suggestion that replay would be used to challenge or correct such calls. But after all the outcry about the average game soaring past the 2:40 mark, even a limited application of replay would slow things down.
