I find myself agreeing a little bit with both sides here. I said it earlier that as a traditionalist, and an umpire myself, I don't want to see drastic changes to the roles of the umpires. But, I'm starting to realize that umpires CAN control how good they are. There were two things that happened to me last week, one behind the plate and one at second base, that made me think that the best umpires are mentally tough and can make the crucial decisions, and also the correct decisions, on the fly. I kind of froze, and wish I had the calls back. It's hard to be completely neutral, completely accurate, AND completely fair. The mental side of umpiring is what causes these guys to make mistakes. I froze on an infield fly that ended up being dropped by the shortstop, and then I narrowed my strike zone just a little to allow one team to tie it up, even though they lost anyway in extra innings. The umpires that cannot control the mental aspect of what it takes to be an MLB umpire have to be weeded out. If and when they are, the overall performance of umpires will drastically improve.
