Not to pick a nit, but which errors are the egregious ones? Seems like the team that gets the smelly end of the stick would have an argument using egregious as the standard.
Video used as an instructional tool is a wonderful teaching aid. Video used to "correct an error" is a slippery slope. Where does it end? I am not suggesting that the clock get turned back to the days of one umpire for the whole field (unless he is equipped with a monitor
), but we need to let these guys umpire. They should be working hard because this is their chosen profession and they have a passion for the craft, not because they are trying to be as good as the eye in the sky.
