How can you know that? Do you have access to an edited-down version from an alternate reality?
It's a pretty simple conjecture.
The book was bloated, he and others (including myself) felt that it could have been trimmed down and kept the same effectivness.
This is the same problem that happened with Robert Jordan I'm told, he starts the series as a nobody so the editor can dictate what can and cannot be published and you get a lean story. As the story becomes more popular the creator have more power and the editor lets more stuff stay.
Honestly this series could have been trimmed down big time starting with the 3rd book, in my opinion.
and I do disagree a bit with Aaron. I think that
Jon Snow made the best decisions as Lord Commander he could make in those situations, he was making the hard decisions to survive. He just didn't appease his brothers and it led to his downfall, which will lead to the downfall of the brotherhood before this is over.
