No. The only revelation was the deal Brady didn't take (which you guys have broken down as not as selfless an act as it might first appear).
They interviewed the Krafts, Brady (nothing on Deflategate from him, only on the 2016 season, so pretty blah), the two NFLPA lawyers, then a bunch of players about Brady. They didn't talk to Goodell, Belichick (in one interview they said they didn't even try) or the ball boys. They talked to nobody in the scientific community, and only mention the science when talking about The Wells Report in Context. They softpedal Kraft's concession and try to resuscitate his public standing, and they lionize the lawyers. They have both Goodell and Belichick as villains, and throw Don Yee under the bus for telling Brady not to trust Wells with his phone.
What's troubling is they run with the conventional wisdom set by some of the reporting over the years. They believe McNally and Jastremski DID tamper with the balls. They believe Wickersham's report that Kraft ordered Belichick to trade Garoppolo (despite Curran, Howe and Daniels saying that report was wrong). They say Spygate was very serious, and Belichick should have been suspended for it. And the BS Goodell-looking-for-a-daddy-surrogate was as unsupported as it was nauseating.
A good ten chapters of the book are backstory of the principals. Yawn. It's the kind of book you write when you're on a tight deadline and trying to get it produced as a movie. And even with all the science extracted, it's still gonna be a deadly dull movie.
