Re: 10 minutes with Bill James
I think the point isn't that "Bill James didn't know this, therefore people who spend their study time in statistical analysis have this same blind spot." The point I get is that, like any discipline, only using a certain tool or tools will lead to a much less rounded view of the discipline being studied than gathering data from various sources and angles.
A fitting analogy would be walking into a car dealership ready to buy a new car, having done all the research on the car's specs. Then you sit in it and drive it and find it isn't comfortable and rides awful. So, you don't why the specs say one thing but your ride tells you another, but I'm guessing you don't buy the car. Or at least you would be wise not to. There was value in knowing the specs, but it did not tell you all you needed to know about that car. The test drive ("kicking the tires" as they say) gave you vital information that helped make a wise decision.
