Was Stan's method to simply dry hop in secondary?
I don't think he was really advocating for one method or another. He was pointing out that dry hopping before the beer was removed from the yeast will produce different results than dry hopping with the beer on the yeast. It's up to each of us to try it and decide which method is appropriate for us.
I'd go so far as to say it's up to each of us to decide what is right for each particular brew. different results = different tools in the toolbox.
