I know most won't agree with me on this, but seeing as Brett Favre is my namesake on here (and the pseudo-religion I've coined using his name), I feel a need to defend both him and the Packers organization.
Who do I blame for this whole debacle? The media.
Each year, the media began a "Brett Favre watch" to see when and if he would announce retirement. Most players have the benefit of waiting the duration of the off-season with little or no scrutiny (like Johnathan Ogden of the Ravens, or Steve McNair). Instead, Brett felt additional pressure, as people began to proclaim him a "media queen" for drawing out the process of retirement each year.
In reality, Brett should have the right to that time without the media hounding him. Most players have an entire offseason to think about their future. This time, Brett was tired after a long season, and didn't want to put the team through the usual histrionics, and decided to call it a career in March.
While this was clearly a mistake (since Favre has obviously shown that he wants to come back), you can't blame Favre for that.
You can't blame the Packers for their actions either. They need to give Aaron Rodgers a chance to play. He showed flashes of brilliance in the Cowboys game, and was more efficient then the great #4 that game. The Packers decided to move forward assuming Favre was retired, a fair assumption considering how adamant he was in his initial retiring.
Now, Favre wants back. Yet the Packers have Rodgers and Brian Brohm waiting in the wings. They can't let him back on, since they have already moved on, they can't release him, due to the cap hit, and they can't trade him to any old team, as many teams might face the Packers. Yet, they have done nothing wrong.
This is all the media's fault, yet no one will ask what their role is in this. They've long scrutinized everything Favre did, asking whether "he still had it" for years, even when it was clear that while he had indeed lost a step (and what older QB hasnt?), it was the supporting cast around him which was preventing his skills from shining through.
This is the media's fault, plain and simple. I will of course root for the Packers, and if a team ends up signing Brett (other than the Vikings, Bears or Lions), then I'll probably root for them too, as a sort of surrogate team to the Green and Gold.
