Last week's conference, combined with the start of Passover, has caused me to get behind in the self-promotion department.

My latest commentary for Marketplace was last Friday, and discussed the Oakland A's and Billy Beane five years after the publication of Moneyball:

The popularization of sabermetrics has left Beane with less of an advantage -- it's harder to find diamonds in the rough when everyone else is mining the same territory. The A's are not struggling because of "Moneyball"'s failure -- they are struggling because of its success.
