GREEN BAY, Wis. (AP) -- Milk bottles in carnival games are meant to be knocked down.

MVP quarterbacks are not.

Green Bay's offensive line has had its hands full all season as it tried, often unsuccessfully, to keep Aaron Rodgers from looking like a tackling dummy. The Packers' most precious commodity was sacked an NFL-high 51 times during the regular season, almost twice as much as New England's Tom Brady (27).

And it doesn't figure to get any easier in Saturday night's NFC divisional game in San Francisco. The 49ers' front seven is one of the most brutish in the NFL, and just the sight of Aldon Smith or Justin Smith is enough to make a quarterback wince.
