ESPN's Stats & Information furthers the point by proving Williams is one of the NFL's most impactful and efficient players. Williams averages a productive .73 sacks per game the past five seasons, which translates to nearly 12 sacks every 16 games played. But staying healthy is key.
Williams hasn't played a full 16-game season since 2009. He's missed 14 games total the past two years, including 11 last season following a pectoral injury. Before that, Williams never missed a game his first five years in the NFL.
The Bills are obviously secure with Williams' injury history. Otherwise, they wouldn't be comfortable giving Williams a six-year, $100 million contract with $50 million guaranteed. It is the richest contract ever for a defensive player and shows the Bills are serious about winning next season.
It is likely that Williams simply had freak injuries two seasons in a row in 2010 and 2011. But Buffalo needs that run of bad luck to end this year, because Williams is a productive game-changer when he's on the field.
