Rantanen cut it to 2-1 when he tapped in a Nathan MacKinnon pass from atop the crease at 2:14 of the second period.
"I just tried to go to the net and stop there, and we had a couple of long shifts where the defense got tired," Rantanen said. "Nice passes."
Perfetti pushed it to 3-1 when he one-timed a cross-crease pass from Blake Wheeler at 9:44.
"That line (Perfetti, Wheeler, Pierre-Luc Dubois) went a little under the radar; they had a really good game," Arniel said. "They spent an awful lot of time in the offensive zone. That was probably the best game I've seen Cole play just through exhibition and the first couple. He was real good, real smart with the puck, and [made] real good decisions. And when he had to get back, he did a good job. That line got rewarded with good work."
Rantanen cut it to 3-2 on a one-timer from Bowen Byram at 16:26, and Nichushkin tied it 3-3 on the power play at 18:27 when he finished a give-and-go with Rantanen from between the circles.
"[Nichushkin is] playing like he did last year. He's skating," Rantanen said. "He's a really big guy. Hard to get the puck off him, so he's doing well, and he's scoring on his chances too. So, good to see that."
NOTES: Forward Nikolaj Ehlers was a late scratch due to a nagging injury, according to Arniel. … Pionk's winner was his first NHL overtime goal. He is the first Jets defenseman with a multigoal game since Tyler Myers on Feb. 16, 2019. … Rantanen has 168 goals and moved past Alex Tanguay for 10th in Avalanche/Quebec Nordiques history. … MacKinnon had his multipoint game streak end at three but had an assist to extend his point streak to four (two goals, six assists). … Colorado scored on its only power play and leads the NHL at 53.9 percent (7-for-13), but it allowed a power-play goal for the fourth straight game and is last in the NHL on the penalty kill (7-for-14, 50 percent).
