"He's a pretty good goal scorer, so I gave it to him," Gustafsson said.
Kane's second goal of the game, with 2:18 left in overtime, gave the Chicago Blackhawks a 5-4 victory over the Detroit Red Wings on Wednesday night. Kane extended his point streak to 19 games and helped the Blackhawks recover after blowing a 4-1 lead in the third period.
Dylan Larkin and Andreas Athanasiou scored two goals each for the Red Wings, who tied it late in the third. But Kane fired home the pass from Gustafsson in overtime, beating goalie Jonathan Bernier for his 38th goal of the season.
"It really didn't feel good from 4-1 on, because we didn't have a lot of possession and we weren't creating chances," Kane said.
Artem Anisimov, Brandon Saad and Alex DeBrincat scored for Chicago in the first period. The Blackhawks have won 10 of their last 12 games, and this was the seventh time in that span that they scored at least five goals.
Chicago is now tied with Colorado for the last playoff spot in the Western Conference.
"Well, I'd rather be in than out," coach Jeremy Colliton said. "We still need to work on our game. Our game isn't where it needs to be for us to compete in the playoffs, and we're going to have to play better to get the points we need coming down the stretch."
Kane trails league leader Alex Ovechkin by just four goals now, although his goals Wednesday were his only points of the night. His assist streak ended at 17 games.
Chicago beat Ottawa 8-7 on Monday, and the Blackhawks went through another high-scoring night against Detroit. Anisimov made it 1-0 after only 99 seconds, but Larkin answered for the Red Wings a few minutes later.
Saad scored his 21st goal of the season, and DeBrincat's 33rd made it 3-1 before the end of the period.
In the second, Kane came down on a 2-on-1 break with Jonathan Toews. Kane took the shot himself, beating Jimmy Howard to make it 4-1. Howard was then replaced, having allowed four goals on eight shots.
"Sometimes it's just not your night. That doesn't mean it's on him," Detroit coach Jeff Blashill said. "If Kane is going down on a 2-on-1, he's scoring on lots of goalies. I thought DeBrincat's shot was a great shot, I thought Saad's shot was a great shot."
Larkin brought the Red Wings within two with his 26th of the season, and Athanasiou made it 4-3 when he scored on the power play with 14:37 left in regulation. Athanasiou lifted the puck from behind the goal line, next to the net, and it bounced off goalie Cam Ward and in.
The Red Wings had their goalie pulled when they tied it with 1:26 left in the third. Mike Green appeared to mis-hit a shot from near the blue line, but Anthony Mantha corralled the puck to the left of the net and slid it across the goalmouth to Athanasiou, who had an easy shot from the other side.
"We weren't happy at all with how we played in the first two periods. We made it an easy night for them," Larkin said. "I felt like we were waiting for things to happen. They were getting bounces and scoring easy. The way we played in the third, it was a great comeback."
