it's not that ESPN doesn't have people who know advanced metrics. rob neyer and keith law certainly do, buster olney does a little bit (though for a vanderbilt guy, he's still way to married to small ball and "traditional" stats), gammons did, i believe kurkjian does to some extent. but espn isn't going to start running features about UZR and WAR if 95% of their viewers don't know what those things are and don't want to know. they're a business and they cater to the casual baseball fan and the set-in-their-ways baseball fan; baseball prospectus caters to the much smaller segment of the population that is really into baseball and has an open mind for advanced metrics. Pretty much, but you're missing one minor component. In an effort to try to market ESPN Insider as something worthwhile (instead of just the paid version of rotoworld that it was), they've started paying some of the better baseball sites like BA, BP, Fangraphs, etc... for early or exclusive access to some articles. That way, they get to keep us geeks and our stats separate from ESPN-proper, but still manage to exploit us.
