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. The 1973 season would be the last season in which games from non-league clubs counted in league 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.[3]
In a unique twist, the team with home field for the NASL Championship Game determined the date and time the game was to be played. When the Dallas Tornado won their semi-final, setting up the final with Philadelphia, they chose August 25 as the date of the game. 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. The move paid off as Straub headed home the second goal in a 2–0 win with under five minutes remaining in the final.[4]
