The Green Bay Packers' Clay Matthews must rebound from last season's career-low sack total to make his fourth Pro Bowl if the Pack expects to make it to the playoffs. His success is even more crucial to Green Bay's chances than Aaron Rodgers'.
Rodgers is obviously a key factor to the Packers' success, but a quarterback is only as good as his defense. Especially considering the new roles Matthews has been given this season.
Despite his poor campaign in 2011, Matthews is still one of the top defensive players in the NFC North. And an off season for Matthews is still better than most LBs in the league.
