The 1989-90 season was a season of firsts for the Ball State men's basketball program. The team was in its first season under head coach Dick Hunsaker. It became the first team in Mid-American Conference history to win back-to-back regular season conference championships and back-to-back conference tournament titles. The 1990 Cardinals also became the first MAC team to reach the Sweet 16 of the NCAA Tournament in its current format. To this day, no other Ball State team has ever advanced that far in the tournament. The following paper is a narrative account of the 1989-90 season. Through newspaper clippings and interviews with former players, I have attempted to piece together the story of the greatest season in Ball State basketball history.
