Dan Marino is the only player on this list that has not won a Super Bowl. Being that this is the greatest quarterbacks of all-time and not quarterback with the most rings, Marino set standards for other up and coming quarterbacks.
Marino was putting up modern-day numbers back in the 1980s. His best season came in 1984 when he passed for 5,084 yards, had 48 touchdowns, and 64.2% completion rate. Peyton Manning is the only other player to have a 5,000 passing yard and higher than 48 touchdown season. In his 17 seasons, Marino was the leader in passing yards five times.
