While we twiddle out thumbs, PackerReport.com provides some context, and it sounds like some people in the organization are ready to move on without Brett.
According to Mortensen, the Packers source said the team would be reluctant to allow him to return because "Brett retired for the right reasons." Plus, the Packers have spent the offseason tailoring the offense to Rodgers' strengths, and selected two quarterbacks in April's draft.Still, it's not entirely out of the realm of possibility; as PackerReport.com notes, Favre's salary no longer counts toward the cap, the Packers didn't spend the freed-up money this offseason, and seventh-round pick, quarterback Matt Flynn, could move to the practice squad if Green Bay decided to rejigger the depth chart to accommodate Favre.
UPDATE: Hmm. Evidently, Favre wanted to come back, the Packers said, no thanks, prompting Favre to ask to be released. The Packers again said, no thanks. Weird (via Pancake Blocks).
Of course, it's all speculation at this point. Cornerback Al Harris admitted to Mortensen that Favre "has the itch to come back and play," but also conceded that "Aaron [Rodgers] is our quarterback ... Brett's retired..."
Interestingly, Rodgers told Jim Rome last week that he wouldn't rule out a Favre comeback, but he didn't think it would be in Green Bay. Of course, this is the same guy who spent the last few days telling Packers fans to shut it -- before declaring his love for them all -- so either Rodgers is just making stuff up, or he actually knows what he's talking about. Definitely one or the other, though.
