Pro Football Focus put out offensive line rankings for the 2015 season. The Jets did not fare well.
26. New York Jets (13th)
Pass-blocking rank: 22nd
Run-blocking rank: 25th
Penalties rank: 19th
Stud: By virtue of his teammates playing so poorly, the strong run blocking of James Carpenter made him an easy pick.
Dud: Poor in the run game and allowing too much pressure, Breno Giacomini did not have a good year.
Summary: Once a dominating group, this was the year that things finally turned, and the Jets line morphed from productive to problem. Nick Mangold and D’Brickashaw Ferguson just aren’t the players they once were, and there aren’t enough factors to overcome that. This line needs some good, young talent.
It is difficult to argue with any of that. I do wonder how much of Mangold's slip in production was due to him playing hurt, though.
There has been a perception that the Jets were a bad run blocking team but a good pass blocking team because of how few sacks they allowed. It did seem like there was a lot of pressure. Ryan Fitzpatrick did a good job working around it by moving in the pocket and scrambling at times. It seems PFF shares this analysis.
