Question: What conference did William Alexander "Bill" Curry's team join after their last year as competing as football independents?
Context: Dale Hubert "Herb" Sies (January 2, 1893 – October 17, 1954) was an American football player and coach.  He was born on January 2, 1893 in Ames, Iowa and attended Davenport High School.  He enrolled at the University of Pittsburgh, where he played football as a guard.  Sies was named a consensus All-American in 1917.  Seis played five seasons in the National Football League (NFL) and its predecessor, the American Professional Football Association.  Sies began his professional playing career with the Cleveland Tigers in 1920 for whom he started one game.  The following season, he played for the Dayton Triangles as a right guard.  That season, he started in nine games, and the following year, he started in eight games.  In 1923, he both played for and served as the head coach for the Rock Island Independents.  Sies coached his team to an 8–2–3 record to finish 12th in the league.  He started in eight games for the Independents and made good three field goals and eight extra point attempts.  That season, "Collyer's Eye" magazine named Sies to its All-NFL second team.  In 1924, he returned to Dayton for his final season.  He made one field goal attempt for the Triangles. The 2004 UCF Golden Knights football team represented the University of Central Florida in the 2004 NCAA Division I-A football season.  Their head coach was George O'Leary, in his first season with the team.  It was their last year in the Mid-American Conference, in the East Division.  The Golden Knights would join Conference USA for the 2005 season. The Big Blue River Conference was an IHSAA-mandated conference featuring schools from North Central and East Central Indiana.  It operated from the 1968-69 school year until 1988-89.  Five of the original seven schools came from the East Central Conference, four directly, while Tri was formed from the consolidation of ECC member Spiceland.  Morton Memorial, the last remaining ECC member in 1969, would join the conference that year, along with Hamilton Southeastern.  The nine school format did not last long, as Morton Memorial left after one season, and Hamilton Southeastern had outgrown the conference and left by 1972.  The conference briefly returned to nine schools in 1977, as Lapel and Shenandoah joined from the folding White River Conference.  However, North Decatur left three years later, as the new expansion left them geographically isolated.  Morristown would follow suit in 1985, as the school dropped football.  The conference would split in 1989, as Lapel and Shenandoah would help reform the WRC, New Palestine and Triton Central would move to the Rangeline Conference, and Tri was accepted into the Tri-Eastern Conference.  Knightstown and Eastern Hancock were left as independents, though both would join the WRC six and eight years later, respectively.
