Relative Athletic Score is an independent metric created by Kent Lee Platte, which grades a prospect's measurables from 0 to 10 against every player tested at their position since 1987. It is not produced by, affiliated with, or endorsed by Athlete Innovations. Published here because it corroborates testing we recorded ourselves.
