 There is also a Major League Soccer team called the Chicago Fire, and there are/were also NBA teams called the Memphis Grizzlies (2001–present) and Charlotte Hornets (1988–2002, 2014–present) (the nickname "Hornets" was used for minor league baseball teams in Charlotte long before the WFL entry; also, the "Grizzlies" name for the Memphis NBA team was in use when the franchise was still in Vancouver, although the city's previous history with the nickname might have been a factor in the basketball team's decision to keep it).The Jacksonville Sharks and Portland Thunder names were later revived for teams in the 2010 revival of the Arena Football League, with the indoor Sharks (outlasting its namesake by several years) having since moved to the National Arena League.The American Football Association was conceived as a successor to the WFL, and in some newspapers was even referred to as the "New WFL".
