Green Bay faces the Bear next week, correct? However, New England faces Arizona. I think benching Favre is understandable, but either him or Brady could light it up next week. With two guys as close as that I think you would have to play matchups.
Last year, Favre came out with a terrible performance, not even mediocre, so if you expected him to repeat last years numbers, this whould be a good sign, especially against one of the Green Bay's tougher opponents this year.
