Clay Matthews is the linchpin for the Packers defense and has been since the day he was drafted in 2009. For Clay's first five seasons in the NFL he was the pass rush for the Green Bay Packers. If Clay didn't play well, odds are the defense didn't either. Last season, largely due to the addition of Julius Peppers and the improvement of Mike Daniels, the Packers were able to move Clay to inside linebacker halfway though the season for portions of games in an effort to improve the run defense. This move was to help the defense as a whole and when they needed a pass rush, they could still let Matthews do that from different areas on the field.
