I'm no John, but I believe the three chapter submission is more an insight into the strength and style of your writing. You don't need to introduce your entire cast and outline the entirety of your plot in the first few chapters of your book, and you shouldn't try to rearrange your novel with this mentality either. After a publisher is hooked by your writing and the beginnings of your story, they'll request the entire manuscript and make a decision to publish based on that.
