Of Letestu's 16 goals during the regular season, 11 were scored on the power play. The key to his success is simple.
"Just the willingness to shoot the puck," he said. "We've got a lot of guys on that power play, they're playmakers. Connor [McDavid] and Leon, especially. Pass-first guys. I know when the puck comes to me, deliver it, get it to the net. It's been going in."
The Ducks essentially held McDavid in check; McDavid had one assist and didn't have a shot on goal until the third period.
But McLellan will tell you that a deep, multi-pronged attack is what the Oilers are going to need to continue this playoff run.
"I think it's essential," he said. "You don't, at least I believe, just win on just one superstar. You can go back and talk about how Chicago did it. Or Pittsburgh or Los Angeles, those years.
"It wasn't just done on [Jonathan] Toews, [Anze] Kopitar and [Sidney] Crosby back. It was deep. It was timely.
"Letestu has done it for us on the power play all year. He's very nifty and crafty and finds pucks and to have [Larsson] score two. We've found different heroes so far in the playoffs on any given night. That's the way it is done."
