Deion Luwynn Sanders Sr. (//; born August 9, 1967) is an American former football and baseball player, who works as an NFL Network analyst. He was inducted to the Pro Football Hall of Fame on August 6, 2011.
Nicknamed 'Prime Time', he played football primarily at cornerback, but also as a kick returner, punt returner and occasionally as a running back or wide receiver. He played in the NFL for the Atlanta Falcons, the San Francisco 49ers, the Dallas Cowboys, the Washington Redskins and the Baltimore Ravens, winning the Super Bowl with both the 49ers and the Cowboys. An outfielder in baseball, he played professionally for the New York Yankees, the Atlanta Braves, the Cincinnati Reds and the San Francisco Giants, and participated in the 1992 World Series with the Braves. He attended Florida State University, where he was recognized as a two-time All-American in football.
The 40-yard dash is a sprint covering 40 yards (36.58 m). It is primarily run to evaluate the speed of American football players by scouts, particularly for the NFL Draft but also for collegiate recruiting. A player's recorded time can have a heavy impact on his prospects in college or professional football. This was traditionally only true for the "skill" positions such as running back, wide receiver, and defensive back, although now a fast 40-yard dash time is considered important for almost every position. The 40-yard dash is not an official race in track and field athletics and is not an IAAF-recognized event.
The origin of timing football players for 40 yards comes from the average distance of a punt and the time it takes to reach that distance.]citation needed[ Punts average around 40 yards in distance from the line of scrimmage, and the hangtime (time of flight) averages approximately 4.5 seconds. Therefore, if a coach knows that a player runs 40 yards in 4.5 seconds, he will be able to leave the line of scrimmage when a punt is kicked, and reach at the point where the ball comes down just as it arrives.
