Neither is Cam Newton nor Aaron Rodgers.
On a given day, one of these guys (and others not named above) may play perfectly, but in reality, there are still flaws and areas for improvement, though assigning criticism for each proves a difficult task.

Newton, on the other hand, does it with his feet—setting a record for rushing touchdowns by a quarterback in 2011, his rookie year.
The incomparable Brady is the master of accuracy and intelligence, reasons why he is always amongst the league leaders in passing yards and touchdowns.
Then there's Peyton Manning, who can game-plan better than any other active quarterback, exposing defenses for more than a decade now.
