Passer rating (known as passing efficiency or pass efficiency in NCAA football) is a measure of the performance of quarterbacks or any other passers in American football and Canadian football. There are at least two formulae currently in use: one officially used by the National Football League and the Canadian Football League, and one used in college football. Passer rating is calculated using each quarterback's completion percentage, passing yardage, touchdowns and interceptions.
A perfect passer rating in the NFL is 158.3. A perfect passing efficiency in college football is 1261.6.
The NFL's complex passer rating was devised in 1971 by a special committee headed by Don R. Smith, an executive at the Pro Football Hall of Fame. Don Weiss created the passer rating. Prior to that, the NFL had struggled with how to crown a passing king using multiple statistics.
The calculation of the NFL passer rating involves more steps than the NCAA formula. In order to establish a maximum value for an NFL player's passer rating, a separate calculation needs to be completed involving each of the following four categories: Completion Percentage, Average Yards Per Attempt, Percentage of Touchdown Passes, and Percentage of Interceptions. If the result in any category is less than 0, the given result should be 0. If the result in any category is greater than 2.375, the given result should be 2.375. This makes the maximum possible quarterback rating for the NFL 158.3. A perfect rating requires at least a 77.5% completion rate, at least 12.5 yards per attempt, a touchdown on at least 11.875% of attempts, and no interceptions.
Andrew Austen Luck (born September 12, 1989) is an American football quarterback for the Indianapolis Colts of the National Football League (NFL). He played college football for Stanford University, won the Maxwell Award and Walter Camp Award as college football's player of the year, and was recognized as an All-American. He was the runner-up for the Heisman Trophy in both 2010 and 2011. He was named the Offensive Player of the Year in the Pac-12 (Pac-10) Conference in both 2010 and 2011. CBS Sports draft analyst Rob Rang called Luck the best prospect he has ever scouted, while the Kansas City Star puts him in line with LeBron James and Bryce Harper as "the most hyped amateurs in recent sports memory". Although widely projected as the No. 1 selection in the 2011 NFL Draft, Luck decided to return to Stanford for his redshirt junior season.
Luck was born in Washington, D.C., the son of Oliver Luck, current athletic director and a former quarterback at West Virginia University and former NFL quarterback for the Houston Oilers, and Kathy Wilson Luck. Andrew Luck spent his early childhood in London, England and Frankfurt, Germany, where his father was general manager of two World League of American Football teams prior to becoming president of the league. He is the oldest of four children, Mary Ellen, Emily, and Addison, who currently reside in Houston. In London, he attended The American School in London.
