It is funny how everybody talks about stats. It won't help though. Spygate is full of stats. In many of those stats it showed how ridiculous far outside the Pats are operating. But it didn't matter then and it won't matter now.
I really recommend reading that book. In the past I wanted people to read that book to show how far Spygate actually reached and why the conclusion was what it was. Now I want people to read it because it is now a very good add-on the Deflategate. It also explains very well why the Patriots will get away with Deflategate.
It is also ironic that the new policy about teams bringing their own footballs happened just around the time when Spygate 'ended'.
It is an eye-opening book and well worth the read.
