Dan Marino set the single-season record for passing yards back in 1984, by throwing for 5,084 yards, while a member of the Miami Dolphins.
New Orleans Saints quarterback Drew Brees came real close to breaking that record in 2008, when he threw for 5,069 yards.
This season, Brees, along with Green Bay Packers quarterback Aaron Rodgers, and Tom Brady, of the New England Patriots, are all threatening to eclipse the 27 year-old mark.
So far this year, Brees has thrown for 3,326 yards in ten games, while Brady has passed for 3,032 yards in nine games, and Rodgers has accumulated 2,869 yards in nine games.
Of the three, which one has the best chance to break Marino's record?
