Most defenses can't stop Green Bay's passing game, anyway, but the league's better units -- i.e. those playing in January -- have shown some ability to slow down this unbalanced attack. Maybe Aaron Rodgers just airmails this team from here to eternity, but we've seen him take a beating behind Green Bay's shaky line.
Benson wasn't about to set the world on fire, but he was signed to bring some legitimacy to the running game, which would help the passing game disguise itself better. From that angle, his absence weakens the Packers down the stretch.
