It all comes down to the granularity and reliability of the data. The analysis should shift to the pitch-by-pitch data. This would actually have a direct benefit to the hitter/pitcher, as how they approach each PA is hugely dependent on the count. Carlos Delgado said that he keeps a log of every one of his PAs. I'd love for every pitcher and batter to do the same, log where they were trying to throw, where the batter was looking for the pitch. It's these things that would make for the holy grail, and give us the ultimate. But, these secrets are important to the pitcher and batter. So, if the Delgado's can donate their diaries after their careers are over, we can gain a huge insight into pitchers and batters. The other area would be fielding, and positioning. Capturing the ball game in 4-D (including a time component), we can know where a fielder and ball is at all times, and how, and how fast, the fielders move towards a ball. The problem here is that this data will be the province of 30 teams instead of 1000 analyst. And the giga or terra bytes of data will be so overwhelming. Frustrated? No. Annoyed maybe. And not at the "traditionals", but also to the "new guard". Everyone wants to have their opinions heard, and the look into the forest for whatever numbers support them. Some people do a great job at it, and some don't. I would much prefer if people voiced their opinions separate and exclusive of numbers. One thing that we really hit hard in The Book is that numbers require alot of interpretation and a margin for error, since performance stats are just samples of something true. And all samples have margins for error. In short, the numbers don't necessarily tell you what you think they tell you. But, what your eyes see gives us great insight that can be used to pair up with the numbers. That's why I love the Fans' Scouting Report. Exactly, Stats don't replace judgment, they aid in judgment. They potentially validate or invalidate judgment. But there always is a confidence factor that has to be taken into account. Thanks, This chat has been great.
