Its probably more likely he would replace Gruden, assuming he jumps back into coaching, on MNF. It depends on how bad he wants to be around the game. Favre is just coaching near where he grew up (and his father coached him), so its more of a hobby thing there. I think that niether one will end up coaching at a pro level. Few even mediocre QBs do (Starr, the Harbaugh brothers?), for whatever reason.
I am a Packer backer, but like hell if I think that game is a lock for GB. And whoever said AP wasn't fumble prone this year, he tends to do it post season and outdoors (he played almost no games outside since winter started yet this season), but its possible his recovery has made him better at protecting the ball in general. Biggest deal is if Woodson's return actually allows them to bring more men down to the line and if the Packer D actually tackle for a change. I can't believe that GB got picked by all the sports writers, given rescent Lambeau playoff history. Also, I am suprised so many of them are picking the Ravens, who basically backslid into the playoffs almost as bad as the Texans did.
