Quarterback rating isn't the one and only measure about a player's performance, but it often paints a pretty accurate view of how quarterbacks -- and for Cam Newton, it's awfully telling.
Newton's QB rating has declined in each of his five starts this season:
Week 1 vs. Miami: 100.7 Week 2 vs. Seattle: 94.6 Week 3 vs. Las Vegas: 73.8 Week 6 vs. Denver: 51.6 Week 7 vs. San Francisco: 39.7
So it's no surprise that Newton's slide is reflected in our weekly QB Power Rankings entering Week 8 of the NFL season. For a player who had cracked the Top 10 earlier this season, Newton now finds himself right near the bottom of the barrel.
It's a different story for Tom Brady, who has cracked the Top 5 on the heels of another stellar performance.
