There is a reason for this:
EJ is a rookie, the Jets have good DBS, CJ is the only offensive weapon the Bills have that teams are really afraid of, and SJ is the only receiving threat that defenses must respect. So, other than that it is Hackett's fault...
As for Pettine, what kind of a loser DC can't completely shot down an offense wit NO starting DBS in an already thin defensive backfield?
