Sorry, but I don't recall all these stories that Duncan broke. So, to me the facts are that he didn't do it unless it's proven otherwise.
I mean, he was the Saints' beat writer. Of course he knows what happened over the years. But, I would also bet that 90% of the people on this board already know everything that Duncan wrote in that book. It's just a history book looking back at the 15 years that Brees was on the team. It was Duncan's way to make money off of Brees' career.
