I don’t think he was hoodwinked. The book was written > a year ago. The docuseries was filmed in November, no? All of this content has been around for a while now. It’s been Belichick’s choice to shape his own narrative in the docuseries.
Having read the book and listened to multiple podcasts with Benedict and Hamachek, I don’t think the purpose of either the book or series is to rehash games, highlights, and Super Bowls. The Dynasty is about the (New England) holy trinity of Brady, Belichick, and Kraft. There is a 20-year arc for each of the three and the combined trio that is described in both mediums. That’s why, imo, some combination of the three is featured in each episode of the docuseries, but not necessarily all of them (e.g. Brady’s absence in E6). You don’t need Brady to tell the story of the BB/RKK arc related to Hernandez. Similarly, RKK is a little superfluous to the Brady ACL tear-focused E5 (“I saw a young man sobbing” is about all he contributes to that episode.)
I love the fact that the docuseries gathers voices from the team and organization (Law, Bruschi, Bledsoe, Adams, Pioli, Moss, etc., and McCourty/Branch/Lloyd/Welker/Gronk for E6) to provide color and context for the main characters. Branch and Lloyd (“Wes talked to me like he’d seen a ghost.”) were particularly riveting in E6.
But I don’t think BB is getting a bad edit; it’s just hard to critique individual episodes as representative of the overall arc. For example, the first four episodes highlight how BB built Dynasty 1.0 based on his foundational principles, his Cleveland/NYJ experience and Brady’s unexpected rise. E5 highlights the gap years where the team is in transition and BB loses the ability to reach the team and get them to play the way he wants, despite Brady’s continued excellence. E6 includes the re-tooling/reinvigoration of the roster (enter McCourty/Gronk/Hernandez), but the continued lack of ability of BB to enforce consistent discipline on the team (after the 2009 Jetsons snowstorm issue and Ravens playoff debacle, you had Hernandez running around acting crazy in practice and BB not doing anything about it, to the irritation of Welker, Brady, et Al) remained through the Hernandez murder spree. Future episodes will get into Dynasty 2.0, L'Affaire Garoppolo ("We all know Tom's age..."), the ultimate consolidation of power by BB, and the fracture of relationships among the three. I think it will be positive for BB up through 28-3, but all downhill from there to depict “The End”.
edit: looks like the series was announced in Feb. 22, so it makes sense that it was filmed in that year, per
