I don’t think he changed his mind at ‘the last moment.’ It was clear the Packers were looking to go in a different direction and I have nothing but sympathy for the position this has place Aaron Rodgers in, but really, if the man wants to play let him. That really should’nt be a moral conundrum for people.
Even if the Packers had made that decision to go another direction it would have been more helpful to them (and Favre) if he had let them know he wanted to play this season much earlier.
