The Bills defensive line struggled in 2015. They finished with the second lowest sack total in the league with 21 after coming off a league-high 54 the year before. For the sake of this article, we are going to include defensive tackles, defensive ends, and outside linebackers into one “defensive line” article.
Part of the reason for the decline in sack numbers was the team’s ability to adjust to Rex Ryan’s defensive scheme from the one ran by Jim Schwartz the two years prior.
On top of that, star defensive end/outside linebacker Mario Williams only gave effort when he wanted to, as documented by Pete Prisco of CBSSports.
