The Southside football teams have won seven state championships at the state's highest classification (1983, 1988, 1991, 1992, 1998, 2002, 2006). Four of those titles came under longtime Southside head coach Barry Lunney Sr., who left the school after the 2004 season for conference rival Bentonville. Jeff Williams took over the program and led Southside to their last title in his second year in 2006. In 2008 and in 2009, Southside made a surprising run to the championship game, but fell short to Bentonville in 2008 and Springdale Har-Ber in 2009.
