Walter Camp,
American Football
“ An end cannot tackle as occasionally does a half-back or back, slowly and even waiting for his man, then meeting him low and strong. An end always has to face interference, and good interference will bowl over a waiting end with ease. An end must go up as far and fast as he dares to meet the runner, and when his moment comes—which must be a selected moment—he must shoot in at his man, reaching him, if possible, with his shoulder, and at the same time extending his arms as far around him as possible. ”
