It was on the second day of my combine grind that the Parabolic trainers set up the lines and cones for testing. The three-cone drill, also known as the “L drill,” was among the first we ran, almost immediately after the 40-yard dash.
This was my first time running the drill. There were basics to master, such as where and in which direction to run and at what time. That didn’t even include when to zig, when to zag, when to accelerate, when to pound the brakes or burst through the finish line. All so complicated for a newbie like myself.
