Steve Stanley, Mark Tehan, lack of power and the New York Times Magazine article

I know this is a bit dated, but did anyone get a chance to read the cover story by Michael Lewis in the April 24 edition of the New York Times magazine? It focused on Oakland farm hand Steve Stanley and former Oakland draft pick and current Royals 3B Mark Teahen. Actually, John Sickels was quoted in it. Basically it's a story about two guys who have decided that they are what they are  -- essentially guys who take the ball to the opposite field and not power hitters -- and that all advice to the contrary is not really wanted. If you read the article, are familiar with these guys' history or have any thoughts about the prcoess of trying to take an approach, batting stance, pitching motion, etc. of a prospect and drastically changing it, I am interested in hearing your opinion. I will try to find a link to story for those interested.
