In the team's inaugural season, head coachBill Musselman led the Thrillers to a 35-13 record with a roster featuring Coby Dietrick, Sidney Lowe, Brian Martin, Freeman Williams, Ronnie Valentine, Charles Jones, and Perry Moss. With and advertising budget somewhere between $50,000 and $100,000, the team set a regular season record of 2,946 fans per game that first year. Their cheerleaders were called the Thrillseekers, and dressed in top hats, tails and long black stockings. The Thrillers' original owner was Jeff Rosenberg, a Sarasota restaurateur, who marketed the team heavily. In the postseason, Tampa Bay swept the Lancaster Lightning in the first round and disposed of the Albany Patroons before getting by the Detroit Spirits, 4–3, in the CBA championship series, for which Williams earned MVP honors. The team played its home games at the Bayfront Center in St. Petersburg, Florida.
1985–86 season
Because of a lease dispute during the off-season, Rosenberg moved the Thrillers' 1985–86 home games to the University of Tampa's Spartan Sports Center, a 4,200-seat venue built in 1984, but their regular season attendance dipped to an average of 1,339. With Musselman at the helm, Tampa Bay posted a CBA-best 34–14 record. That season, Thrillers guard Kevin Williams scored 58 points in a game against the Baltimore Lightning. Ten days later, he had a 59-point effort in a playoff game against the Patroons. The Thrillers became the first CBA team to win back-to-back titles, as they dispatched the La Crosse Catbirds in five games.
1986–87 season
In 1986–87, the Thrillers moved back to the Bayfront Center and had another outstanding season, albeit with a new owner, John Tuschuman, head of Fidelity Management Company, which owned and operated residential communities. In January 1987 after only a few games and dreadful attendance, as low as 295, Tuschuman announced that he would seek to relocate the franchise. He then went on to blame the St. Petersburg Times newspaper for not properly featuring the Thrillers with cover stories on the sports page. However the team's general manager, Sandy Smith, revealed that the 1986–87 advertising budget was approximately $30,000 –well below the figures spent in previous seasons. In a bizarre development, the franchise moved out of Florida at the end of the regular season, and became the Rapid City Thrillers. That did not stop the team from another championship run, which ended in a five-game triumph over the Rockford Lightning. The Thrillers were the only franchise in CBA history to ever achieve a three-peat. The Rapid City Thrillers would continue in both the CBA and International Basketball Association until 2001.
