Favre has some deep rooted resentment toward the Packers.
Even though I doubt Favre is in any type of physical shape to play Football he would love nothing more than to attempt to spoil a Packers perfect season.
Adam Schefter of ESPN had this to say.
A source familiar with a certain QB in Mississippi told http://ESPNChicago.com that that QB would listen if the Bears made a pitch.
Either this is legit or ESPN is just trying to drum up some ratings.
It is a bad idea either way, moreso for Brett Favre’s health than anything else. In the end it is more just something to talk about to ignore the fact the Monday Night Football game is terrible.
