It is tempting to say that although the Jets have done a good job addressing their defensive line, they have done nothing to improve their pass rush. That is not completely true. While a 3-4 defense generates its pass rush with hybrid outside linebacker/defensive ends, defensive linemen can certainly help.
Muhammad Wilkerson and Kenrick Ellis are both projected to command consistent double teams. When the linemen command such attention from an opposing blocking scheme, it makes life easier on the other pass rushers. Could the Jets still use a linebacker to get to the quarterback? There is no question that this is the case. They have, however, made moves that will affect the pass rush in a positive manner.
The defensive line was already a strength of the team. Mike Devito and Sione Pouha have come into their own over the past two seasons. Now they have a pair of potentially excellent linemen to help them out.
