Hjalmarsson, an alternate captain, likes how the Coyotes have competed the past two months.
"It's a big difference from the beginning of the season," said Hjalmarsson, who led the Coyotes with three blocked shots on Monday to bring his season total to 94 in just 39 games. "We've got a totally different confidence and just a different feeling in the group. We trust each other a little bit more and we have two great goalies so it doesn't matter who's in the net, we know we're going to have a great effort in the back end and that's always a great feeling for the defensemen to know that. We've been playing great and taking a lot of points. We're just going to try to keep going here."
• Arizona trailed Edmonton, 3-1, midway through the third period, but rallied to tie the score. Christian Dvorak started the comeback by netting his 12th goal of the season at 11:31.
The Oilers seized momentum early by scoring a shorthanded goal, an even-strength goal, and a power-play goal during a 9:03 span of the first period.
"We started to play our game in the last 40 minutes," Dvorak said. "I thought the first 10 minutes were pretty good and the last 10 minutes (of the first period) we fell asleep there and they got three goals. It was good resiliency by our group."
• Antti Raanta was scheduled to start in net for the Coyotes and led the team onto the ice for warmups. That plan changed.
Per Head Coach Rick Tocchet, Raanta was "a little tight" so he decided to start Darcy Kuemper instead. Playing on short notice, Kuemper stopped 32 of 36 shots in his second start with Arizona.
"It's my job to be ready to go no matter what and I felt pretty good in there," Kuemper said. "... It was a great job by the group to stick with it, battle back and take it to overtime. That was huge. Unfortunately, we couldn't finish it off."
