It was common practice at this time for colleges and universities to include non-collegiate opponents in their schedules, with the games recognized as part of their official record for the season, and the February 12, 1913, game against the Maryland Athletic Club counted as part of Georgetown's won-loss record for 1912-13. It was not until 1952, after the completion of the 1951-52 season, that the National Collegiate Athletic Association (NCAA) ruled that colleges and universities could no longer count games played against non-collegiate opponents in their annual won-loss records.^[12]
