What leads you to believe this Les?
Supposedly after Spygate Goodell and Belichick had an agreement or understating that BB was going to come clean in his press conference and admit what he did was wrong and apologize. And as we know he didn't do that, he deflected and said he just misunderstood the rules. We know that is a lie because Goodell sent out a memo expressly forbidding filming because originally the Packers (I think it was them) were caught, then the Patriots were warned. And he flagrantly ignored the memo, then bullshitted Goodell about coming clean.
Goodell was, according to reports, livid with him for not doing the mea culpa thing because it made the NFL look even worse.
He hosed Roger, and we know if you lie to Roger he wants his pound of flesh, ask Vick.
40 people are/were/have been investigating this thing. FORTY. That's a big number and when I heard it the first thing I though was "he wants revenge". IMO he wants to catch Belichik so he can smash him. Kraft and Goodell may be friendly, but I can assure you there is no such warm and fuzzy between BB and RG.
If the NFL can link someone, anyone, in the Patriots organization to this he will find a way to hold Belichik responsible under the "ignorance is no excuse" mantra. Just like he did when SPayton lied to him about Bountygate.
Lying to Goodell has proven to have dire consequences and BB better hope and pray that nothing can link a team member to those footballs being under inflated on purpose.
