Athleticism is calculated using different metrics including player weight, 40-yard-dash, vertical jump, shuttle, and more. It is adjusted differently for each position to account for what matters most for NFL production.

40-yard-dash times are one of the most popular, and most overhyped, metrics in the NFL. Running Backs and Wide Receivers are aiming for that 4.4 time.

Speed Score is a weight adjusted 40-yard-dash that accounts for the size of the player. A good weight adjusted speed score has a strong correlation to success with larger running backs and smaller wide receivers.
