The Coyotes jumped to a 2-0 lead on Friday before the game was four minutes old, but the Oilers chipped away at the deficit and gradually gained control.
"When we get a start like that there, 2-0, we should be able to play a little better defensively and try to take advantage of that start," Hjalmarsson said. "…They have a couple guys who their individual skill level is extremely high and you have to be aware of who's on the ice because those guys can do some special things. That's not an excuse; we should have gotten away with a couple of points here today after the start we had."
Head Coach Rick Tocchet was pleased to see Hjalmarsson back on the ice.
"Nik was good," Tocchet said. "He was steady for us."
Friday's game was Arizona's 44th game of the season, but just its first with a healthy defense corps. Luke Schenn, who hadn't missed a game all season, was the odd man out as a healthy scratch.
Tocchet is eager to see what the unit can accomplish now that all of the defensemen are healthy at the same time.
"We're going to rely on them a lot," Tocchet said. "It's a defense corps that when they're all healthy, if they can step it up another level, we can compete."
