I usually find that those types of people have never put on a pair of skates or picked up a stick (or ball, bat what have you). They just don't see it from another perspective or have the personal experience of participating in what they think they know all about. I see that sort of thing every day on a popular baseball board i belong to. They all try to be Bill James prodigys. While these people can be extemely intelligent and organized, they also tend to be very robotic, stubborn and condescending/rude to anyone who speaks other to them. Then when they are wrong, they are almost bipolar in their reactions. Not sure how much of that pertains to any of the stat people here, but usually they are birds of a flock.
