Whether or not Brady cheated I do not know. What I DO know is that he is not the supposed greatest of all time.
He is a system quarterback. Without the system he would be average or maybe a journeyman.
Right.
Having the aptitude to read a defense, change the play on the fly, and throw darts to his receivers is a pretty good system.
He is a system quarterback.
Other than the vocabulary, the offense changes every season, and sometimes every game. His strength is that he can change from one offensive scheme to another at the drop of a hat, to exploit an opponent’s weakness.
They “system” is called game-planning.
