"In a widely lauded speech in New York in January 1922, Fielding Yost, head coach at the University of Michigan, said that paying men to play football 'robs the great American game of its greatest character-building qualities. The ideals of generous service, loyalty, sacrifice, and whole hearted devotion to a cause all are taken away. The game is robbed of the exhilarating inspiration of achievement merely for achievement's sake.'"
This quote seems quaint given the spectacle of Lane Kiffin abandoning Ole Miss in the midst of the school's greatest achievement to sign a $13 million per year contract with LSU. And Kiffin lacks the achievement of either SEC or national championships.
"At his [George Halas] suggestion, the APFA [American Professional Football Association] changed its name at an owners' meeting in Cleveland on June 24, 1922. 'I lacked enthusiasm for our name,' Halas wrote, because the word 'association' connoted minor league status in baseball. He suggested National Football League, explaining that baseball's National League was the sports most established, respected circuit. The other owners approved unanimously."
