David Harris RAS
David Harris was drafted by Jets with pick 47 in round 2 in the 2007 NFL Draft out of Michigan.
He recorded a Relative Athletic Score of 7.82, out of a possible 10.0. RAS is a composite metric on a 0 to 10 scale based on the average of all of the percentile for each of the metrics the player completed either at the Combine or pro day.
He had a recorded height of 6022 that season, recorded as XYYZ where X is feet, YY is inches, and Z is eighths of an inch. That correlates to 6 feet, 2 and 2/8 of an inch or 74.25 inches, or 188.595 centimeters. This correlates to a 6.57 score out of 10.0.
He recorded a weight of 243 in pounds, which is approximately 110 kilograms. This correlates to a 7.46 score out of 10.0.
Based on his weight, he has a projected 40 yard dash time of 4.78. This is calculated by taking 0.00554 multiplied by his weight and then adding 3.433.
At the Combine, he recorded a 40 yard dash of 4.62 seconds. This was a difference of 0.16 seconds from his projected time. This forty time correlates to a 8.67 score out of 10.0.
Using Bill Barnwell’s calculation, this Combine 40 time gave him a Speed Score of 106.68.
The time traveled between the 20 and 40 yard lines is known as the Flying Twenty. As the distance is also known, we can calculate the player’s speed over that distance. The time he traveled the last twenty yards at the Combine was 1.93 seconds. Over 20 yards, we can calculate his speed in yards per second to 10.36. Taking into account the distance in feet (60 feet), we can calculate his speed in feet per second to 31.09. Breaking it down further, we can calculate his speed in inches per second to 373.06. Knowing the feet per second of 31.09, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 21.2 in the last 20 yards of his run.
At the Combine, he recorded a 20 yard split of 2.69 seconds. This correlates to a 8.49 score out of 10.0.
We can calculate the speed traveled over the second ten yards of the 40 yard dash easily, as the distance and time are both known. The time he traveled the second ten yards at the Combine was 1.09 seconds. Over 10 yards, we can calculate his speed in yards per second to 9.17. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 27.52. Breaking it down further, we can calculate his speed in inches per second to 330.28. Knowing the feet per second of 27.52, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 18.8 in the second ten yards of his run.
At the Combine, he recorded a 10 yard split of 1.6 seconds. This correlates to a 8.99 score out of 10.0.
The time he traveled the first ten yards at the Combine was 1.6 seconds. Over 10 yards, we can calculate his speed in yards per second to 6.0. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 19.0. Breaking it down further, we can calculate his speed in inches per second to 225.0. Knowing the feet per second of 19.0, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 13.0 in the first ten yards of his run.
At the Combine, he recorded a bench press of 23 repetitions of 225 pounds. This correlates to a 7.54 score out of 10.0.
At the Combine, he recorded a vertical jump of 33.0 inches. This correlates to a 5.46 score out of 10.0.
At the Combine, he recorded a broad jump of 811, which is recorded as FII or FFII . where F is feet and I is inches. This correlates to a 1.34 score out of 10.0.
At the Combine, he recorded a 5105 or 20 yard short shuttle of 4.29 seconds. This correlates to a 5.98 score out of 10.0.
At the Combine, he recorded a 3 cone L drill of 7.25 seconds. This correlates to a 5.45 score out of 10.0.
This player did not record any measurements at their pro day that we were able to find. If they recorded Combine measurements, they stood on them.
