There are some unknowns however.
The first will be how Quinton Coples will perform off the edge. All signs, at least in my opinion, are positive. Everything on video, everything I have read, makes him a perfect fit in the Rex Ryan/Mike Pettine system. The questions still are out there as far as his motor. Will it run all the time? If it is, Coples, and the edge pass rush, will be just fine. It will have some issues if the motor questions are legit.
Now, the bigger question?
Can they defend against the tight end?
This is one we really don’t know yet, and we won’t know until the season begins.
