American Football 1921 [EPUB ebook] 

"Smashmouth Football"That term came from the way the game of American Football was coached and played at the end of the 19th Century and the early years of the 20th century. Coach Daly compared the game of football to war and that’s how he played and coached the game. Almost all of the well known, best coaches of the time used basically the same principles in training and game planning as Coach Daly describes in this book. "The defensive line man may take a low position inside his opponent and make a straight charge with one hand on the throat and the other on the face, thus moving the opponent by steering his head. Or he may, in charging, step to the outside, striking a blow on the side of the opponent’s head." Charles Dudley Daly
