I agree with this. I think the electronic zone is a fascinating idea, and I really like the tennis-style proposals thrown out here. The biggest issue to me, though, is that the "human element" (which I can appreciate the value of) sometimes resorts to acting like blind authority. If all umps committed to using the performance review system to get better and were incentivized to do so, that would be just fine. This doesn't have to be an all-or-nothing answer. Technology can be used to help improve the quality of the human element without removing it completely. Now, maybe most umps do or are doing this, or maybe the incentive system is working and I just can't see it because I'm not behind the scenes, but it does seem like a lot of umps have trouble admitting they missed one. Even more, it seems like the league trots out the same umps year after year, and those guys keep acting the same and missing the same calls. That's an issue. Players are to blame a bit too, especially when they complain about borderline pitches. Even an electronic zone is going to have a fuzzy border, and we should recognize the technology's margin of error (lately, on Brewer broadcasts, FoxTrax looks real bad to me, as if the CF camera angle is throwing off the true location of the pitch--maybe the reliability of the tech just isn't good enough yet), especially since the vertical limits of the zone are harder to track than the fixed lines in tennis. Save the vigorous dissent for the really bad ones. There are enough of those to let everyone blow off steam.
