The main site's weekly mock draft has the Jets ending up with Baylor defensive lineman Phil Taylor.
30. New York Jets: Phil Taylor, DT, Baylor. If Scott Pioli doesn't like Taylor's tape enough to take him at No. 21, then Rex Ryan will like Taylor's size and athleticism enough to take him here. Finding a suitable replacement for Kris Jenkins is a rarely-cited option for the Jets.
I am not so sure how much I agree with the reasoning. The Jets have their replacement for Jenkins. It is Sione Pouha. It is also Mike Devito. The Jets could stand to add another quality prospect on the defensive line, though. Taylor has a lot of potential. Believe it or not, Pouha is actually a bit older than Jenkins so the Jets will have to address the nose tackle position for the future. It can take a few years to develop a guy at the position. so this would be a good time.
