|The Green Bay Packers take their turn in the examination room after beating San Francisco.|
Linebacker Clay Matthews has one sack over the past three games, and even that one was a non-contact credit when Minnesota Vikings quarterback Brett Favre slid behind the line of scrimmage. He is no longer the NFL's sack leader, now ranking second by a half-sack behind Miami Dolphins defensive end Cameron Wake. It's a fact that Matthews has been nursing a shin injury. Is that to blame for his dip in production? Have defenses caught up to him? Or is it the most likely scenario: That sacks come and go over the course of a 16-game season? I couldn't tell you, although I'm most inclined to believe the latter scenario.
