NFL quarterbacks - additional information
The position of quarterback is probably the most important position in football. Almost all possessions on the offensive end start with the quarterback, who is the main decision maker on the offensive side of the ball after the ball is snapped to him at the start of each possession.
The importance of the position is reflected by the high salaries quarterbacks earn in the National Football League. Amongst the ten highest-paid players in the NFL in 2013, six were quarterbacks (highest average annual salary over the length of the current contract). Joe Flacco, for example, quarterback of the Baltimore Ravens, makes 20 million U.S. dollars per season. According to the NFL Players Association, the average playing career length for NFL quarterbacks is at around 4.44 years. The average career length of players in the NFL is 3.3 years.
The most successful quarterback in NFL history in terms of playoff games won is Tom Brady, who has won a total of 22 playoff games. The other quarterbacks who have won ten or more playoff-games are Joe Montana, Terry Bradshaw, John Elway, Brett Favre, Roger Staubach, Peyton Manning, Troy Aikman and Ben Roethlisberger.
