David Cobb RAS
David Cobb was drafted by Titans with pick 138 in round 5 in the 2015 NFL Draft out of Minnesota.
He recorded a Relative Athletic Score of 4.55, 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 5107 that season, recorded as XYYZ where X is feet, YY is inches, and Z is eighths of an inch. That correlates to 5 feet, 10 and 7/8 of an inch or 70.875 inches, or 180.0225 centimeters. This correlates to a 5.55 score out of 10.0.
He recorded a weight of 229 in pounds, which is approximately 104 kilograms. This correlates to a 8.93 score out of 10.0.
Based on his weight, he has a projected 40 yard dash time of 4.7. 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 4.81 seconds. This was a difference of 0.11 seconds from his projected time. This forty time correlates to a 0.66 score out of 10.0.
Using Bill Barnwell’s calculation, this Combine 40 time gave him a Speed Score of 85.56.
At his pro day, he recorded a 40 yard dash of 4.73 seconds. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.
Using Bill Barnwell’s calculation, his Combine 40 time gave him a Speed Score of 1.77.
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 2.09 seconds. Over 20 yards, we can calculate his speed in yards per second to 9.57. Taking into account the distance in feet (60 feet), we can calculate his speed in feet per second to 28.71. Breaking it down further, we can calculate his speed in inches per second to 344.5. Knowing the feet per second of 28.71, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 19.6 in the last 20 yards of his run.
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 his pro day was 2.01 seconds. Over 20 yards, we can calculate his speed in yards per second to 9.95. Taking into account the distance in feet (60 feet), we can calculate his speed in feet per second to 29.85. Breaking it down further, we can calculate his speed in inches per second to 358.21. Knowing the feet per second of 29.85, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 20.4 in the last 20 yards of his run.
At the Combine, he recorded a 20 yard split of 2.72 seconds. This correlates to a 3.36 score out of 10.0.
At his pro day, he recorded a 20 yard spit of 2.72 seconds. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.
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 1.08 seconds. Over 10 yards, we can calculate his speed in yards per second to 9.26. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 27.78. Breaking it down further, we can calculate his speed in inches per second to 333.33. Knowing the feet per second of 27.78, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 18.9 in the second ten yards of his run.
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 his pro day was 1.03 seconds. Over 10 yards, we can calculate his speed in yards per second to 9.71. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 29.13. Breaking it down further, we can calculate his speed in inches per second to 349.51. Knowing the feet per second of 29.13, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 19.9 in the second ten yards of his run.
At the Combine, he recorded a 10 yard split of 1.64 seconds. This correlates to a 3.4 score out of 10.0.
At his pro day, he recorded a 10 yard split of 1.69 seconds. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.
The time he traveled the first ten yards at the Combine was 1.64 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 18.0. Breaking it down further, we can calculate his speed in inches per second to 220.0. Knowing the feet per second of 18.0, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 12.3 in the first ten yards of his run.
The time he traveled the first ten yards at his pro day was 1.69 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 18.0. Breaking it down further, we can calculate his speed in inches per second to 213.0. Knowing the feet per second of 18.0, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 12.3 in the first ten yards of his run.
At the Combine, he recorded a bench press of 17 repetitions of 225 pounds. This correlates to a 4.45 score out of 10.0.
At the Combine, he recorded a vertical jump of 38.5 inches. This correlates to a 9.21 score out of 10.0.
At the Combine, he recorded a broad jump of 1001, which is recorded as FII or FFII . where F is feet and I is inches. This correlates to a 7.86 score out of 10.0.
This player did not have a recorded 5105 or 20 yard short shuttle for the Combine in the RAS database.
At his pro day, he recorded a 5105 or 20 yard short shuttle of 4.55 seconds. This correlates to a 0.54 score out of 10.0.
