2004 Stats: 4,557 yards, 49 touchdowns, 10 interceptions, 121.1 passer rating
Peyton Manning's 2004 season was arguably the most magical season a quarterback has ever had. He threw for a then-record 49 touchdowns, breaking Dan Marino's 20-year-old streak of 48 tosses.
Before Manning's 2004 season, his quarterback production had been unseen. Since that year, Tom Brady has thrown for 50 touchdowns, and a few quarterbacks have consistently passed for over 4,000 yards.
But what sets Manning apart was his ability to spread the ball. He had three receivers—Marvin Harrison, Reggie Wayne and Brandon Stokley—with 1,000-plus yards and 10-plus touchdown receptions. Unlike Brady, Manning did not favor one receiver and throw 23 touchdowns to one guy. He spread the field, killed the clock and dazzled defenses.
His '04 season was a shocker, and his quarterback play was like a machine. Due to the fact that his production was unprecedented and that he got everybody heavily involved in the offense, he edges out Brady's 2007.
