According to several sources, including the New York Daily News, the New York Jets will perform more of a 4-3 defense, especially against division rivals. Ever since Rex Ryan took over the Jets he has deployed several types of defenses (3-4, 4-3, Blitz, Cover, and others) with success. However, for the Jets to play a single defensive set is somewhat different from the standard norm for Rex Ryan.
But don't fret. Many NFL teams have adopted more a pass first, run, second stance, and the Jets are developing a younger defensive line made up of Quinton Coples and Calvin Pace as the edge rushers with Muhammad Wilkerson, Kenrick Ellis, and Mike DeVito making up the rotating trio of the inside. This change can be widely credited to Quinton Coples as the Jets drafted him with the 16th pick in hoping to fulfill the pass rush that the Jets have long looked for.
