Great article on perhaps the future of how fans may think or talk about baseball.
The PitchFX data system provides an incredible wealth of information and quite a lot of disect. I think it will be especially valuable for teams in scouting of pitching and hitting tendencies.
Dixieflatline has done an great job breaking down from the data in the last year and a half, but we are just at the beginning. When you can track every pitcher over the course of his career, you will have a plethora of data on all these players. This may make the careers of pitchers even shorter. If hitters know what is coming before the pitch is thrown, and approximately what part of the plate the pitcher targets in that situation, it may be a huge advantage to the hitter. Of course it works both ways, and maybe some batters would be overthinking of exactly what the next pitch will be, instead of just swinging.
Although the article says it is the end of the box score, I don't think this will catch on to be in the average baseball fans vocabulary in the next 20 years. Maybe I am just too old fashioned, but I think with the incredible amount of data is very interesting, but does not appeal to a wide audience. That being said, it will change the game, whether fans understand it or not.
