MLB is dragging it's feet on this for sure. Rules are sacred and shouldn't be tampered with and technology is bad and should be shunned. But then the teams are using the technology to take advantage of the rules or lack thereof. I love the history of baseball, but the sport isn't going to survive if it continues to treat every thought of change as an apocalyptic event. Change isn't good or bad, it's just inevitable. Fans will survive it if we get out in front of it and learn how to adapt our fandom. This is one thing the NFL has on MLB, they aren't shy about changing rules on a whim to make things quicker, safer, more fair or more watchable. Sometimes they work, sometimes they don't, but then they're not shy about changing them back either.
