In my opinion, I believe these are both top-10 defenses in 2012. The Cowboys have the better defensive line and linebacker unit, but I give the Jets' cornerback duo the edge over the Cowboys' new additions. The safety position is a major concern for both teams. I would give the slight overall edge to the Cowboys because of their ability to get after the quarterback. As I wrote the other day, rushing the passer has become the key element in championship defense.
