The production wasn't the problem, though. There were uncharacteristic defensive miscues, like slightly hesitating to send a pass along the blue line in his own zone before letting go just to be intercepted, leading to a breakaway.
"If I miss eight months, it didn't allow me to train," Letang said. "I was only allowed to skate the last week of the summer. I had a lot of catching up to do, and the bad thing about it was that it was during the season when I had to do it. I think I was a work in progress."
During that time, the errors were noticeable.
"It was not so much, 'Oh, I can't play anymore.' It was lapses," Letang said. "It was one good shift, one bad one, one good shift. At the end of the day, people remember, and I remember, my bad shifts. But I was totally capable of doing the job. I was able to be myself, but it was just a question of doing it for 60 minutes and being committed to the details."
Letang, averaging 25:22 of ice time this season, tried to remain aggressive and trust his talent, which had made him a finalist for the Norris Trophy as the best defenseman in the NHL in 2013. Sometimes it betrayed him and he would turn over the puck, but knowing Sullivan hadn't lost faith helped him maintain confidence.
"He kept playing me," Letang said. "He knew I'm the type of guy that builds up a workload and that's how I get better. He kept having confidence I would improve my game by playing me and playing the minutes I should be playing. I think that was the biggest thing."
Taking Letang out of the lineup wasn't something the Penguins ever considered, Sullivan said.
"There was never a time that we questioned it because he's so important to this team," Sullivan said. "In the big picture, it was important to allow him to play through it. … He's a terrific person and he cares so much about this team and trying to help this team win. He's a hard critic of himself. That's one of the things we love about him."
