Manual / Hard Copy
This historical looks at the evolution of offensive line technique and rule changes as it applies to the use of extended arms and hands. From 1888 to 1985, line coaches determined their philosophies and blocking technique to the rule stating that hands needed to stay in contact with the body and forearms parallel to the ground. Prior to 1888, interference, for the purpose of moving the football, was no more than a pushing and shoving contest.
