40 Yard Dash

40-yard dash

From Wikipedia, the free encyclopedia This article needs additional citations for verification.

Please help improve this article by adding reliable references. Unsourced material may be challenged and removed. (November 2008) 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 in the 40 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. Punts average around 40 yards in distance, 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.

Timing method and track comparisons

In terms of judging a person's speed, the best method of timing is through lasers which start and stop the times when passed through. A laser start (from a stationary position) is more accurate for measuring pure speed as it does not register a runner's reaction time. However, the method of timing a 40-yard dash can affect the accuracy by as much 0.5 seconds (with the manual stopwatch method). The National Football League (NFL) did not begin using partial electronic timing (started by hand, stopped electronically) at the NFL Scouting Combine until 1990.[citation needed]

In track and field races, the runner must react to the starting gun, which takes approximately 0.24 seconds, based on FAT timing. For electronically timed 40-yard dashes, the runner is allowed to start when he wishes, and a timer hand-starts the clock. This aspect means that comparisons with track times are impossible given that a reaction time is not factored in. Furthermore, the use of hand-timing in the 40-yard dash can considerably alter a runner's time; the methods are not comparable to the rigorous electronic timing used in track and field.

Jacoby Ford, who ran a 4.28 s in the 2010 NFL Combine, had a collegiate best of 10.01 s in the 100 meters.[1] Justin Gatlin, who ran 9.85 s for a gold medal at the 2004 Olympic 100 metres, before being banned from the sport for abuse of performance drugs, has a verified 40-yard dash best of 4.42 s.[2] This reflects the discrepancy in a runner's calculated time when using different timing methods. However, the differences between the timings can be attributed to the nature of the 100 metre race. Runners during the 100 metre variety decelerate towards the end due to fatigue. Gatlin, being an Olympic sprinter, would be better conditioned for the 100 metre race.[citation needed]

Interesting. Didn't know about the punt.

What is the 3 cone drill good for?

3 cone drill

From Wikipedia, the free encyclopedia The 3 cone drill, or three cone drill, is a test performed by American football athletes at the NFL combine. It is primarily run to evaluate the agility, quickness and fluidity of movement of players by scouts, particularly for the NFL Draft but also for collegiate recruiting. While not as highly regarded a test as the 40 yard dash, it is still an important barometer used by NFL personnel to compare players.

The drill

The name "3 cone drill" is derived from the fact that there are three cones used to distinguish the path for athletes. Three cones are placed five yards apart from each other forming a right angle. The athlete starts with one hand down on the ground and runs to the middle cone and touches it. The athlete then reverses direction back to the starting cone and touches it. The athlete reverses direction again but this time runs around the outside of the middle cone on the way to the far cone running around it in figure eight fashion on his way back around the outside of the middle cone and finally finishing back at the starting cone. The total distance traveled is about 30 yards. Athletes are timed for this whole procedure. This drill is primarily used to determine a player's agility.[url=http://en.wikipedia.org/wiki/3_cone_drill#cite_note-0]
