I have watched a lot of Jets games this year and last year and they are not wrong. The Jets are not getting a lot of pressure on opposing QBs at all. Even their sack leader last year, Maybin, got most of his sacks on coverage sacks where Revis forced opposing QBs to hold onto the ball for 5-7 seconds and Maybin would get easily blocked initially and then come back from out of nowhere to make the sack.
Also, I have seen the opposing teams starting to use the overloaded blitz against the Jets. You have seen a lot of draws or screens getting huge gains running away from the overloaded sides.
Rex's first two years, the overloaded blitz has worked great. Last year and this year thus far, not so much.
I wouldn't mind seeing the Pats blitz more, but the Jets' defense is not a defense to emulate. They are average at best and give up more points than the Pats do even after holding the Colts to 9 points yesterday. Yesterday was the first time they consistently pressured the QB all season (or really in the last two seasons).
