that joke of a league that the RimRockers originally played in? I found an article that listed 218 teams that have folded since the league started. These are the teams under "A" several with an Arkansas connection:

Albany Thunderdawgs: Could not reach an arena deal.
Albuquerque (Native America): Team to be made up of all Native Americans.
Alexandria Wind Jammers, Va.
Anaheim Roadrunners
Anderson Champions: Two attempts.
Arkansas Aeros: Began play in 2006. They played their home games at the All-Star Sports Arena in Springdale, Ark. They ceased operations on March 15, 2007. The team compiled a 25-2 record during their short existence. The team had absorbed the operations of their brother franchise, the Arkansas Rivercatz following the unexpected closure of the ‘Catz’ headquarters location hotel in Pine Bluff.
Arkansas Fantastics: Began play in 2007 in Fayetteville, Ark. The team was co-owned by former America’s Next Top Model contestant Furonda Brasfield and Arkansas Razorbacks all-time assist and steals leader Kareem Reid.
Arkansas Rivercatz: Based in Pine Bluff, Ark. The team was originally called the Little Rock Rivercatz, and was scheduled to play in Little Rock at the Barton Coliseum. The team had a 34-game schedule with 16 home games on the slate to be played at the Pine Bluff Convention Center. They compiled a 17-7 record and were ranked no. 15 in the ABA Power Rankings before the team’s headquarters, the Royal Arkansas Hotel and Suites suddenly went out of business, forcing the team to merge operations with its brother franchise, the Arkansas Aeros.
Arkansas RimRockers: Joined NBA Development League, currently inactive.
Atlanta Mustangs
Austin: Never named.
