Rex Ryan 3-4 defense

[halidouepics]

From a personnel perspective, how hard is it to change from a 4-3 to a 3-4?

One of the reasons Wade got the head job in Dallas is because they were built to run the 3-4 and Jones thought it would be much easier to find a coach that ran that system than have to overhaul the roster.

Interstingly, Gregg Williams is a disciple of Buddy Ryan and Rex is his son, so I'm wondering if that makes the transition any easier as far as terminology. Considering Rex runs the 3-4 (which I didn't know) I'm thinking it will be an entirely different system, terminology and all. Am I way off here?
