Favre has NOBODY to throw the ball to. Look at the injuries just to the WR and RB positions.
-Javon Walker - done week one
-Robert Ferguson -injured most of the season and a huge disappointment when he did play.
-Terrance Murphy - teams 2nd round pick that was just starting to get time when he got hurt
-Bubba Franks has been in and out of the lineup all year with injuries
-Ahman Green - starting RB -horrible year before the injury
-Najah Davenport - #2 RB -disappointing before the injury
-Chaz Williams - some benchwarmer that wouldn't do anything
-Samkon Godo -future starter?

I don't think Green Bay is trying to run Favre out of town, or force him to retire. I just think everything that could have gone wrong did. He has no choice but to throw into double coverage because NO receivers ever get open.
