We lose sight of just how amazing Mannings accomplishments are because we are living through them, we enjoy laughing at his infrequent slipups, and his consistency makes us take what he does for granted. The last five seasons have been variations on a 4,000-yard, 30-touchdown, 15-interception theme, with his team winning at least 10 games and reaching the playoffs every year. Even for the great quarterbacks in history, a five-year run of playoff appearances, statistical excellence, and perennial Pro Bowl berths would be the centerpiece of a career. While this five-year run does include Mannings two Super Bowl appearances, it comes after two MVP awards, a record-breaking 49-touchdown season, two passing yardage crowns, a 14-2 season, a 13-3 season, and two 12-4 seasons. If Peyton Mannings career had started in 2006 - if everything before that happened in the USFL - he would be a Hall of Famer and one of the 15 or so best quarterbacks in history (his record would be similar to Steve Youngs in many ways). But his career started in 1998, and thats why he is arguably the greatest quarterback ever, and unquestionably one of the top five.
