Fielding Yost, Football for Player and Spectator… (1905)
“ If the practice is not interesting enough to burn an indelible impression of every rudiment of football into the player's working knowledge, it is wasted. The coach can best instruct his men by putting on his football suit and illustrating exactly what he wants done, not only in fundamentals, but in team play. Confidence of the members of the team, one in the other, and constant interest in how each comrade is developing will in time form a team spirit, a factor quite as potent in carrying a pig-skin as an extra hundred pounds of muscle. ”
