Joe Petrone was the Drillers general manager for their entire existence. The Drillers were coached in 1979 and 1980 by Hans Kraay, who brought a number of players with him from the Netherlands. After Kraay, Timo Liekoski took over as coach in 1981, while Patrone would serve as the team's final caretaker coach until the team folded at the end of the 1982 season. During the outdoor season, the Drillers played their home games at Commonwealth Stadium, but dwindling crowds during the final year saw the team move to much older and smaller Clarke Stadium, which led to even fewer fans attending the games. The Drillers played their two seasons of indoor soccer at Northlands Coliseum and also at Edmonton Gardens. The outdoor team was characterized by a strong defensive style of play, but their indoor style was built upon a run-and-go style of attack. Attendance for the outdoor games ranged greatly from 10,000 in the early stages of the franchise to 4,000 per game in 1982. By comparison, the more successful and profitable indoor games had attendances ranging between 5,000 and 7,000 paying fans per game in 1981 and 1982. Because the Northlands Coliseum was booked, Game 1 of the 1981 NASL indoor finals was instead played at the slated-for-demolition Edmonton Gardens. On March 2, 1981 the Drillers defeated the Chicago Sting, 9–6, in front of 5,089 fans to lead the series. In Game 2, played five days later, Edmonton came from behind to down the Sting, 5–4, in front of a then-record NASL indoor crowd of 16,257 at Chicago Stadium to sweep the finals and claim the 1981 NASL indoor championship.
In 1982, costs were skyrocketing for the team as they were with a number of the other NASL franchises. In Edmonton's case in particular, the following have been speculated as factors connected with the team's collapse: poor support by local media; difficulties stemming from a tricky deal with the owners of the Coliseum and Commonwealth Stadium relating to the attendance, concessions and parking at the indoor games; and as admitted by John Colbert, the Drillers' business manager in 1982, a business strategy that consisted a "top-down construction" for the team.
