It's relative weakness against weakness, but it will go a long way toward determining Sunday's outcome. Favre needs downfield targets to open up the box for hard-charging RB Adrian Peterson. He's no stranger to eight-man fronts, but those in turn could provide the one-on-one matchups the Vikings exploited so often last season. Favre carved up the Lions twice last season, but Rice was a factor in both games. He'll have to find help from Harvin (if he plays), Berrian and Greg Camarillo, who might have to be a bigger part of the game plan this week.
