Not really shocking.
It's been obvious all along that the Packers don't want Favre back. Aaron Rodgers is GM Ted Thompson's guy, and Favre would not be given a real opportunity to win his starting job. Favre and Mike McCarthy had their conversation on Monday that McCarthy was talking about on Sunday, in which it appears that he made it clear, once again, that they don't want Favre back, and Favre has to be the bad guy and walk out because the Packers won't release him like they should.
He added, "So they can say they welcome me back but, come on, the way they've treated me tells you the truth. They don't want me back, so let's move on. I don't know where it's headed. We'll see."
