The Jets defense was so overrated last year it wasn't even funny. Spectacular front line, but mediocre at best back eight. Teams could and did pass over them a lot. If you could slow down their d-line which was gassed a bit by the end of the season, you could get big passing plays because their secondary was awful. And with Dee Miliner moved to the #1 CB position this year, it could be even worse even with the addition of Pryor in the draft. The Pats had a better pass defense than the Jets.
And CJ2K was a flash in the pan until proven otherwise. He a good back, but just a 1,000 yard back which isn't that special anymore. It has been three years since he put up 2,000 yards and three years since he put up double digit rushing TDs. He certainly makes their RB corp better, but let's not go overboard.
