Terminology of the week

A-11 Offense

An offensive philosophy designed to appear as if all 11 players are eligible receivers. The offense exploits a loophole in the American football rulebook to technically make the formation a scrimmage kick, and the offensive line is spread across the field, all wearing numbers of eligible receivers, in an effort to confuse and deceive the defense. This alignment is an unsportsmanlike conduct penalty against the offense.

ACL (Anterior Cruciate Ligament)

One of the four major ligaments of the human knee. It attaches the front of the tibia with the back of the femur and functions especially to prevent hyperextension of the knee and is subject to injury especially by tearing

Across The Middle

Refers to a passing route where the receiver crosses the center of the field.

Aiding The Runner

An offensive player shall not push, pull or lift the runner to assist his forward progress. The official, using both arms facing down and with hands open and forward at the waist, will make a pushing movement two times. The result is a five-yard penalty for the offense.
