In 2012, the Jets were tied for 25th in the NFL with a team total of 30.0 sacks. The season before, in 2011, the Jets were 17th in the league with 35.0 sacks. In 2010, they tied for eighth in the league with 40.0 sacks.
The team has experienced a precipitous decline in their pass rush over the past three seasons. The front office made moves in the draft, notably the selections of Muhammad Wilkerson and Quinton Coples, to address this need, but they haven't been able to improve on-field performance.
The year's class of free-agent pass rushers offers the Jets the opportunity to improve their defense's ability to get to the quarterback and take the pressure off their secondary.
*Writer's note: While Dwight Freeney and Cliff Avril are both, without a doubt, the premiere DE's in this year's free-agent class, they were left off this list because the salaries they command simply aren't feasible for the Jets given their current cap situation.
