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.
The Jets have not had such a great pass rush since the days of John Abraham, and with the disappointment of Vernon Gholston, the Jets were desperately wanting a pass rusher. This change can also be credited to that the Jets defensive front being relatively young. Coples, Wilkerson, and Ellis are new to the NFL, Pouha is old but does not have many miles on him, and Pace is a respected Veteran. Devito will likely be a viable backup. So this change to a 4-3 doesn't seem so surprising after all. And when you have the best CB duo and one of the best MLB a 4-3 starts to look pretty good.
Quinton Coples will have his name called early, and he will have to shine this year in order to avoid the shadow of Vernon Gholston. Coples is the key to this defense, and if he has a spectacular year then the Jets will make the playoffs.
