Giroux revealed that the team anticipated it, as DeBrincat didn't want to stay with Ottawa for the long term.
"We kind of saw it coming," Giroux said. "It was his decision and we all enjoyed playing with Alex. He didn't want to be here. He didn't see himself here for the next eight years. So that's the business side of hockey that's not really fun. But it is what it is. Now we're going to move on."
DeBrincat declined a contract extension, prompting a trade to the Detroit Red Wings.
The trade involved Dominik Kubalik, Donovan Sebrango, a conditional first-round pick, and a fourth-round pick.
DeBrincat signed a four-year deal with Detroit worth $7.875 million per season. He'll face his former team on October 21st, and fans await his reception at the Canadian Tire Centre with curiosity.
