Changes to speed up pace of play will be welcomed by me. After watching a Sox pitcher stand like a statue for 26 seconds, presumably to keep the first base runner from timing his steal and the batter staying in the box that long, that kind of thing borders on the ridiculous. I am not a fan of the shift driven by front office technical nerds either. They shifted Ted Williams long ago, but now players consult their printouts kept in their hats for virtually every player. Doesn't feel like baseball.
Yes, I'm for technology assisted umpires behind the plate. There is too much variability game to game and in game. With the pitchers throwing ever harder,, the hitter needs to know that balls out of the zone won't be called strikes and the pitchers need to get a fair shake when they do make a great pitch. The technology is currently available to help the umpires make the correct call consistently.
