I believe my reference was to offenses more exotic than the West Coast. WC quarterbacks - Stafford and Rodgers - do just fine.
Hard to judge Cam based on one year. The thing that distinguishes him is that he has a cannon for an arm. Gus didn't run the Air Raid offense that allowed weak-armed qbs - remember Leach wanted Greg McElroy - to throw the ball all over the field and go for 5000 yards passing. I think it will be telling to see how Cam does with progressions, but if he can nail that down and lose the happy feet, he might have a very successful career.
Going to be very interesting to see how a quarterback like RGIII does. I think the idea of mobile quarterbacks will always be important, but given the speed and size of NFL defenses, it's going to be hard to make your bread and butter on that. Another reason why SEC quarterbacks are better suited to the NFL if - IF! - they have the arm strength to handle it.
