The NFL Combine measures players using both 20-yard and 60-yard shuttle drills. The shuttles, much like the 3-cone drill, test speed and acceleration. The only difference is that players are running laterally instead of forming a right angle.
Who can improve draft stock the most: Pass rushers, wide receivers, running backs.
The Rules: The shuttle runs take place between a set of cones. For the 20-yard shuttle, the player starts in a three-point stance and then runs five yards to his right, touches the ground, reverses and runs back 10 yards, touches the ground, before heading back five yards to the finish line. The 60-yard shuttle is similar, but instead of a 5-10-5 pattern, players run in a 10-20-10 pattern to the finish. The extra distance can help test an athlete's endurance in addition to quickness and burst.
Current NFL Combine record:
Cornerback Jason Allen (2006)/ Wide receiver Brandin Cooks (2014) – 3.81 in the 20-yard shuttle
Wide receiver Shelton Gibson (2017) – 10.71 seconds in the 60-yard shuttle
