I agree that anybody who thinks Jeremy Brown = Moneyball should probably stop talking.
I don't think this is quite fair. I read Moneyball last year for the first time, and I was surprised at how prominent Brown is in that book. He is used as one of the main referents for the Beane's/the A's "out of the box" thinking, so I think it's an exaggeration to say Brown does not in some important way represent what the Moneyball approach was about.
I was also surprised to read the As take (at least as interpreted by Michael Lewis) on the drafting of Scott Kazmir and Prince Fielder. If I recall correctly, the As were quite pleased that other teams were selecting Kazmir and Fielder because, as high schoolers, these players did not appeal in the least to Oakland. Probably one of the reasons the Oakland folks are now trying to distance themselves from the book.
