The 1992–93 season was also the first of two national NPSL championship years for the Attack with Rookie Eddie Carmean scoring the game winning goal in the semi-final overtime to send the Attack to finals for the first time.
Kansas City was one of the more successful of the NPSL's teams, though the league itself declined in the late 1990s. In 2001 the league disbanded, and Kansas City and the NPSL's five other remaining teams formed a new league, the second Major Indoor Soccer League. At this time the team renamed itself the Kansas City Comets, after the city's original indoor soccer team. In 2005 the franchise announced that it would not play in the 2005–2006 and 2006–2007 seasons, but hoped to reform thereafter. However, the team did not reorganize by the time the second MISL folded in 2008.
