Talking with Keiton Jones' high school coach today, he gave me some positive test results on the offensive tackle:
30-inch vertical jump
5.4-second 40-yard dash
Sub 4.8-second Pro Agility Test
I threw the numbers into the Relative Athletic Score calculator to see how he graded against Draft eligible offensive linemen years older than him since his vertical is very indicative to his athletic potential, and this is the RAS he received for that leap: 7.98 (out of 10). Of course, his measurements and results will be highlighted in red/yellow, given these numbers are from a 17-year-old prospect.
