I love this "system QB" nonsense. The entire term and concept is pretty silly/stupid.

EVERY offense is a system. EVERY QB operates within a system. Whether a QB is great, good or bad depends FAR more on whether he is a good fit within his system than anything else. You think Brady is going to do really well in a run/pass option offense? How about Cam Newton in the accuracy-dependent West Coast offense?

So some QBs may be more flexible, in that they can succeed in MORE systems, but despite that flexibility, their ceiling may not be as high in ANY system, as one guy might have in ONE particular system.

So who the **** cares about the system? The greatness of a QB is all about his performance within the system that he has. Many times that is the QB being in the right system for him. And GOOD COACHING is literally adapting the system to emphasize the strengths, and minimize the weaknesses, of the quarterback. From that point of view, over a long enough period of time, the system is literally designed AROUND the quarterback, so they are indistinguishable. See Patriots/Brady for a key example of that. Over the 18 years he has started the Patriots have expanded their playbook and shaped it somewhat to emphasize what he does well, and de-emphasize what he doesn't do as well.
