Landry has been absent from the offseason training program and OTAs so far. Teammate Darrelle Revis indicated Landry has had "family issues." Whatever the reason, Landry is going to be playing catch-up when he hits the field.
The Jets defense is very complicated and places a lot of mental responsibilities on the safeties. It's not an easy system to learn. Ryan has not ruled out possibly re-signing Jim Leonhard when the longtime Ryan pupil is healthy enough to play again. (Leonhard is a free agent overcoming knee surgery.)
