Final answer:
The Pro Agility Shuttle, also known as the 4 cone test, is an agility test that was replaced by the L Drill in the NFL scouting combine, aiming to assess an athlete's change-of-direction speed and lateral quickness.
Step-by-step explanation:
The agility test that is also known as the 4 cone test and was formerly included in the NFL scouting combine but was replaced with the L Drill is called the Pro Agility Shuttle or the 5-10-5 drill. This test is designed to measure a player's change-of-direction speed and agility.
In the Pro Agility Shuttle, an athlete starts at the center cone, explodes out 5 yards to one side, touches the line, immediately turns and runs 10 yards across to the opposite side and touches the line, then sprints back through the original starting point. This exercise assesses the quickness and explosive lateral movements of the athletes which are essential in many sports, particularly in football.
