A 300 yard game is generally regarded as a sign that a quarterback has had a very good game. Some quarterbacks go above and beyond that on occasion though. A 400 yard game doesn’t come along every weekend in the NFL, and very rarely do two quarterbacks accomplish it in the very same game.
Here are the five times in history where two quarterbacks have each thrown for more than 400 yards in the same game.
On December 20th, 1982 during a 50-34 San Diego Chargers victory over the Cincinnati Bengals, Dan Fouts again broke the 400 yard mark by throwing for 435 yards while Ken Anderson threw for 416 yards.
In 39-35 Miami Dolphins win over the New England Patriots on September 4th, 1994 Dan Marino threw for 473 yards and Drew Bledsoe threw for 421 yards.
