 Ahmad Childress went undrafted for the NFL in 2004.

He recorded a Relative Athletic Score of 0.87, 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 6057 that season, recorded as XYYZ where X is feet, YY is inches, and Z is eighths of an inch. That correlates to 6 feet, 5 and 7/8 of an inch or 77.875 inches, or 197.8025 centimeters. This correlates to a 9.8 score out of 10.0.

He recorded a weight of 351 in pounds, which is approximately 159 kilograms. This correlates to a 9.95 score out of 10.0.

Based on his weight, he has a projected 40 yard dash time of 5.38. 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 5.26 seconds. This was a difference of -0.12 seconds from his projected time. This forty time correlates to a 2.02 score out of 10.0.

Using Bill Barnwell’s calculation, this Combine 40 time gave him a Speed Score of 91.71.

At his pro day, he recorded a 40 yard dash of 5.23 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 1.37

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 2.15 seconds. Over 20 yards, we can calculate his speed in yards per second to 9.3. Taking into account the distance in feet (60 feet), we can calculate his speed in feet per second to 27.91. Breaking it down further, we can calculate his speed in inches per second to 334.88. Knowing the feet per second of 27.91, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 19.0 in the last 20 yards of his run.

At the Combine, he recorded a 20 yard split of 3.11 seconds. This correlates to a 0.61 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 1.26 seconds. Over 10 yards, we can calculate his speed in yards per second to 7.94. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 23.81. Breaking it down further, we can calculate his speed in inches per second to 285.71. Knowing the feet per second of 23.81, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 16.2 in the second ten yards of his run.

At the Combine, he recorded a 10 yard split of 1.85 seconds. This correlates to a 1.35 score out of 10.0 that when multiplied by ten roughly corresponds to percentile.

The time he traveled the first ten yards at the Combine was 1.85 seconds. Over 10 yards, we can calculate his speed in yards per second to 5.0. Taking into account the distance in feet (30 feet), we can calculate his speed in feet per second to 16.0. Breaking it down further, we can calculate his speed in inches per second to 195.0. Knowing the feet per second of 16.0, we can calculate the approximate miles per hour by multiplying that value by 0.681818 to give us a calculated MPH of 10.9 in the first ten yards of his run.

This player did not have a recorded bench press for the Combine in the RAS database.

At his pro day, he recorded a bench press of 20 repetitions of 225 pounds. This correlates to a 2.81 score out of 10.0.

At the Combine, he recorded a vertical jump of 22.0 inches. This correlates to a 0.0 score out of 10.0.

At his pro day, he recorded a vertical jump of 24.5 seconds. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.

At the Combine, he recorded a broad jump of 702, which is recorded as FII or FFII . where F is feet and I is inches. This correlates to a 0.06 score out of 10.0 that when multiplied by ten roughly corresponds to percentile.

At his pro day, he recorded a broad jump of 710. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.

At the Combine, he recorded a 5-10-5 or 20 yard short shuttle of 4.94 seconds. This correlates to a 0.64 score out of 10.0.

At his pro day, he recorded a 5-10-5 or 20 yard short shuttle of 5.36 seconds. Because he also recorded this metric at the Combine, his pro day did not count towards his RAS.

At the Combine, he recorded a 3 cone L drill of 8.75 seconds. This correlates to a 0.3 score out of 10.0 that when multiplied by ten roughly corresponds to percentile.
