The "green dream team"

Obama's set to announce his environmental "dream team" of cabinet nominees today. Here's my concern with B.O.'s top officials so far: yes, they're all immensely smart, passionate and skilled. But do they know how to be managers? That'll be the key to whether or not they can really do a heckuva job. Has any of them, say, been the Judges and Stewards Commissioner for the International Arabian Horse Association--or something similarly challenging?
