There’s no way to sugarcoat the fact that the Green Bay Packers offensive line is a major concern against the San Francisco 49ers. Quarterback Aaron Rodgers has taken a league-high 54 sacks this season, including the postseason. To state the obvious, that’s a huge problem for Green Bay as they prepare to face one of the toughest front sevens in the league. San Francisco has recorded 38 sacks in the regular season, and, to make the bad news worse, they will be getting back Justin Smith, who has missed the last three weeks with a triceps injury. Though Smith has accounted for just three sacks this season, his presence is instrumental in drawing pressure away from teammates like Aldon Smith, who is second in the league with 19.5 sacks.
