The three-cone drill, 3-cone drill or L-drill is a test performed by American football players. It is primarily run to evaluate the agility, quickness and fluidity of movement of players by scouts. It is most commonly seen at the NFL Combine in preparation for the NFL draft but is also an important measurement for collegiate recruiting. While not as highly regarded a test as the 40-yard dash, it is still an important measure used by team personnel to compare players. It is especially pertinent in the evaluation of pass rushers who must be able to maintain acceleration while working around offensive line players.[1] The drill was invented by football scout C. O. Brocato.[2]
