The AP sportswriters' poll would not begin continuously until 1936. (although, the first time was a one instance publishing in 1934) Frank G. Dickinson, an economics professor at the University of Illinois, had invented the Dickinson System to rank colleges based upon their records and the strength of their opposition. The system was originally designed to rank teams in the Big Nine (later the Big Ten) conference. Chicago clothing manufacturer Jack Rissman then persuaded Dickinson to rank the nation's teams under the system, and the Rockne Memorial Trophy was awarded to the winning university.
In an AP story with the caption "Figure This Out!", the system was explained:
"For each victory of a first division team over another first division team, the winner gets 30 points and the loser 15 points. For each tie between two first
division teams, each team gets 12.5 points. For each victory of a first division team over a second division team, the first division winner gets 20 points and the second division loser 10 points. For each tie between two second division teams, each gets 15 points. For each tie between a first division team and a second division team, the first division team gets 15 points and the second division team gets 20 points. Then, after each team has been given its quota of points its final "score" is tabulated by taking an average on the number of games played."
