And you seem to ignore that the way baseball gets talked about on here is not unique to this site. Go to any Sox forum on the internet, and there will be some people talking about metrics, etc. Also people talking about farm system and prospects. And absolutely some Old School stat folk.

But I know there are dozens if not hundreds of other publications that delve deeper in to the math and the metrics. While that stuff is all good, true and (presumably) accurate, I don't read them as often. Because Baseball Digest is simply more fun to read...
