For all this praise of his pass-rushing abilities, Barnes is not the best run defender. At a svelte 251 pounds, he has trouble setting the edge against bigger offensive tackles, but that's where the Jets' recent drafts comes into play.Barnes is fair in run defense, but it's definitely not his strength. The addition of a player like Barnes, who knows how to play in a Ryan defense and who can be a plus in pass rush, but not be a liability against the run like Aaron Maybin has been in the past is key. Barnes will likely play just a substitutional role, but his ability to pressure off the edge will be key.
They have focused on adding beefy defenders for their defensive line, and while the likes of Muhammad Wilkerson, Quinton Coples and Sheldon Richardson are all regarded as solid interior pass-rushers, they also don't sacrifice size against the run, with all three weighing over 290 pounds. Coples himself has moved to outside linebacker this offseason, and will be providing his rush off the edge along with Barnes.
