In a sport that requires so much precision in so many ways, it's weird that variability is accepted, much less desired by some. I can see that, but isn't it a sport driven more by 'luck' than most others? Not saying imperfect umpires are the equivalent of a bloop single, but something about a pitch on the corner having some percentage of being called a strike, and having small ways to improve that percentage, kinda speaks to the same thing for me. A strike is a strike and a ball is a ball. We have the technology to make it a uniform thing now. It should be done. It's not a luck or grey area or nostalgic thing or whatever you want to spin it as.
