Following the blowout loss to the Patriots in Week 13, during which every aspect of the Jets' defense was exposed, coaches pledged that some changes would be made, with Rex Ryan saying the team has "a zillion corrections to make." Ryan noted that if an opponent has success against you in one specific area, then it is a priority to get that corrected.
One major issue is the lack of a pass rush, but a fix could be coming from an unusual source. Trevor Pryce, who played defensive end for the majority of his 14-year career, has been lining up occasionally at nose tackle, where he is much lighter and quicker than Sione Pouha, the starter at the position. Pryce sacked Carson Palmer for a safety on Thanksgiving playing over the center, showing that his agility and burst haven't eroded over the years, and he could be seeing an expanded pass-rushing role in the coming weeks. The alignment isn't an every-down set; Pouha still will be at nosetackle in running situations.
