Re: Interesting post from Sons of Sam Horn...
There needs to be a balance between both a general knowledge of the game and advanced statistics. Too much of either and not enough of the other can cause problems and frequently does.
FWIW, the same problem exists in the weather field too. I've seen more than a couple of guys read all the weather models number for number and 95% they're wrong. Now if they couple the general trends from the weather models and throw in some theoretical meteorology their forecasts all of sudden becomes much better. There is nothing perfect to forecasts and everybody is wrong sometime no matter what. Baseball is the same way, there is no perfect way to predict a player's performance.
