Rutherford said he thought injuries to forwards Phil Kessel and Derick Brassard, who scored one goal each in the Stanley Cup Playoffs, kept them from reaching their potential. Kessel had various injuries throughout the season, and Brassard had one "that is very difficult to play with," Rutherford said.
Neither Rutherford nor Sullivan disclosed any injuries; Sullivan described Kessel's as nothing significant.
Brassard, who was acquired in a three-team trade with the Ottawa Senators and Vegas Golden Knights on Feb. 23, was meant to become the third-line center. He was dropped to the fourth line during the playoffs after returning from a lower-body injury for Game 1 of the first round against the Philadelphia Flyers on April 11.
Sullivan said Brassard was brought in to add depth at center but could have been used at wing. Brassard said he would welcome any role he is given next season.
"I wasn't playing the same amount of minutes, but I'm standing here today," Brassard said. "I was accepting my role. We had a good team and a good chance to win. I would have played, like, five minutes if I had to."
That attitude prevailed throughout the Penguins locker room. Several players were frustrated with being eliminated but also expressed excitement for returning next season.
In particular, captain Sidney Crosby said he has yet to get over the loss to Washington.
"You want to be playing, still," Crosby said, "but you have to evaluate everything and turn the page at some point and get ready for next year."
