This long piece is perhaps not everyone's cup of tea but here's what I'd consider to be an exceptional article from SI.com. Definitely a must read for anyone interested in the history of the game of football. At the turn of the 20th century, Pop Warner coached at the Carlisle Indian Industrial School when Jim Thorpe was shipped away there by his father. It was a small school that catered to Native Americans, with about 1,000 total students between the ages of 12 and 25. In 1912, Carlisle was to play Army led by future President Dwight Eisenhower. A victory by Army would probably put them number one in the polls. The Indians had installed a new offense full of trick plays and misdirection and had been practicing it all season, but were waiting for this game (the twelfth of the season) to unveil it. This was just the second meeting between the Indians and Army since the Wounded Knee Massacre of 1890 (where the U.S. Army killed 300 members of the Sioux tribe). Pop Warner didn't need to give any motivational speeches: "I shouldn't have to prepare you for this game. Just go to your rooms and read your history books."
