During the season, Tiburones Rojos de Veracruz from Vera Cruz, Mexico, played each of the nine NASL clubs in exhibition games that counted in the league's final standings.
[2] A week before the NASL Final 1973, commissioner Phil Woosnam announced that no team in the league made a profit during the season.
They did this because the NASL loan agreements with players from the English First Division (the precursor to today's Premier League) expired before that date.
[4] Because of this, Philadelphia's two leading scorers, Andy "The Flea" Provan and Jim Fryatt, were on their way back to England when the championship match was played on the 25th.
Despite this, Philadelphia coach, Al Miller, put Bill Straub, a defender who had not played a minute for the club prior to the championship game, into the lineup at forward.
