Tom Brady - 470.0 ypg, on pace for 7,520 passing yards
Cam Newton - 427.0 ypg, on pace for 6,832 passing yards
Philip Rivers - 356.5 ypg, on pace for 5,704 passing yards
Drew Brees - 344.5 ypg, on pace for 5,512 passing yards
Tony Romo - 343.5 ypg, on pace for 5,496 passing yards
That leaves Brady, Rivers and Brees. They are seasoned vets that get great protection. As the season progresses and defenses catch up, these three will continue to adapt and dominate opponents. Watch out for Aaron Rodgers, he could sneak into the record chase as well. He's completing almost 71% of his passes so far.
