If Rex Ryan and defensive coordinator Mike Pettine are going to apply pressure on Tony Romo and the Cowboys offensive line, they need to be able to depend on these two guys and possibly one more cornerback.
The Cowboys have talented receivers like Miles Austin and Dez Bryant; if they let these guys out of coverage, it could cause a big problem, especially if the Jets choose to blitz a safety, leaving their cornerbacks without help.
Since his great 2009 season, Darrelle Revis has not had an interception; last year he was okay on account of his hamstring injury. This year, Revis has no excuse for not being able to cover his receivers, but he did not look like the Revis everyone has gotten used to when the Jets played the Bengals this preseason. There were a few times where rookie wide receiver A.J. Green was able to make a catch and get away from Revis after catching the ball.
Meanwhile, Antonio Cromartie will have to continue to prove himself; his departure from San Diego was due to his laziness, and last year he was able to improve, but he still has a long way to go. Cromartie's inability to play receivers off the line can cause some problems, but as long as he keeps his opponents gains to a minimum, there should be no problem.
A lot of what the Jets do on defense depends on how well these two can cover opposing receivers, and it will be interesting to see how Rex Ryan and Mike Pettine go about attacking the Cowboys on Sunday night.
