Through four games in the 2011 regular season, Green Bay Packers outside linebacker Clay Matthews has just one sack. As the 26th overall draft pick two years ago, he notched 10 sacks in his rookie season, followed by a 13.5-sack performance his sophomore year in the NFL. Opposing offenses have resorted to giving him plenty of attention through chips, double teams, and moving the pocket away from his side. Fans and coaches alike have come to expect an elite level of play from Matthews.
