With a one-goal deficit and four minutes of a man advantage ahead, the Calgary Flames looked to get even with the Chicago Blackhawks.
Four minutes later, the Flames had three shots, no goals and a huge swing in momentum for the visitors.
The Hawks killed off a double-minor by star forward Patrick Kane in the second period, plus seven other minors, in beating the Flames 5-2 at the Saddledome last night.
Flames captain Jarome Iginla admitted afterwards the extra-man unit didn't get the job done in losing to the Hawks for the fourth time this season.
"Personally, I was terrible," said Iginla, who was on the ice for 6:24 of powerplay time.
"I'm a big part of the powerplay and being out there. We had some chances to make a difference and we have to be a lot better. Just all the way around too."
Just how bad was the Flames special teams unit?
With four minutes remaining and a two-goal deficit, Hawks centre David Bolland flipped the puck over the glass to give the Flames another chance.
Even with Miikka Kiprusoff pulled for a six-on-four, the Flames buzzed the net but couldn't get anything happening against Calgary-killer Nikolai Khabibulin.
Hawks forward Troy Brouwer iced it with a shorthanded goal from his own blueline.
"We got outcompeted along the walls tonight ... on the powerplay," Iginla said.
"We are supposed to outcompete teams and make them skate, get them back on their heels.
"Right now, we have to get back to doing that. It starts with me for sure.
"If you can be good on specialty teams, you can get momentum back. We didn't do that and didn't do it all year."
"I have to be a lot better being out there in key situations because I'm not contributing enough."
