The Firebirds garnered international attention in November 2015 when, following an overtime victory over the Oshawa Generals, owner Rolf Nilsen fired the team's entire coaching staff for failing to adequately increase the playing time of his son, H?kon Nilsen, a Firebirds' defenseman described by one NHL player agent as "a borderline OHL player". Prior to the game against Oshawa, the entire team with the exception of Hakon Nilsen met with head coach John Gruden and his staff and were informed that the owner had insisted that his son receive more playing time, and indeed Nilsen ultimately played 17 minutes, including power-play time, in the subsequent game. However, head coach John Gruden has denied that this was the reason for his dismissal. In response to the firings, the entire team, including H?kon Nilsen, stormed into the team's front office, threw their jerseys on the floor, and quit the team in a show of solidarity with the coaching staff.
The player revolt proved to be successful, as less than 24 hours later the coaching staff was not only rehired, but given three-year contract extensions. Following a meeting with OHL commissioner David Branch, Firebirds' owner Rolf Nilsen stated publicly that he had made an "irresponsible mistake" and apologized to the players.
On February 17, 2016, Rolf Nilsen again fired head coach John Gruden and assistant coach Dave Karpa. The next day, OHL Commissioner David Branch suspended Nilsen, as well as his appointees on the management and coaching staff, from hockey operations until further notice. The league also ordered counseling be provided to players, at Nilsen's cost. Nilsen and his staff were then ordered to cooperate with a league investigation and comply with its findings. On April 6, 2016, the OHL suspended Nilsen for five years, with no requests for reinstatement to be entertained for three years. He was also fined $250,000. The league also stripped the Firebirds of their 2016 first-round draft pick. Had Nilsen attempted to get involved in hockey operations while suspended, the OHL could have forced him to sell the Firebirds. The OHL placed the Firebirds under league stewardship and appointed Joe Birch as director of operations. After the five-year suspension passed, the OHL reinstated Rolf Nilsen on April 6, 2021.
