NASL
In December 1967 the USA merged with National Professional Soccer League to form the North American Soccer League, taking the original name of the USA group. As a result of the merger several of the original USA franchises folded. This was partly to avoid some cities having two teams. As a result Toronto City, New York Skyliners and San Francisco Golden Gate Gales were disbanded in favour of their NPSL rivals, Toronto Falcons, New York Generals and Oakland Clippers. The owners of the Gales franchise subsequently merged with Vancouver Royal Canadians and Boston Rovers were relaunched as Boston Beacons. Together with Cleveland Stokers, Los Angeles Wolves, Houston Stars, Washington Whips and Dallas Tornado, these teams then became founding members of the NASL. However, after the 1968 season all of these franchises, with the exception of Dallas Tornado folded. They became NASL champions in 1971 and continued to play in the NASL until 1981.
The idea of importing teams to represent franchises was revived during the 1969 NASL season. Both Wolverhampton Wanderers and Dundee United returned. This time the former represented Kansas City Spurs and again emerged as champions. The latter linked up once again with Dallas Tornado. Two other English League teams West Ham United and Aston Villa represented Baltimore Bays and Atlanta Chiefs while Kilmarnock of the Scottish Football League played as the St. Louis Stars.
