General manager Jim Rutherford and the Pittsburgh Penguins aren't satisfied with a second-round playoff elimination.

After their quest for a three-peat was cut short in May, Rutherford and his club have their sights set on another championship run in 2018-19, and roster changes could be in order with the draft and free agency period on the horizon.

"Yeah, it possibly is easier to move some guys now," Rutherford told Josh Yohe of The Athletic. "Those memories and those accomplishments never go away. But we can't live on those either. We want to win again. So, there's a real chance we'll make a couple of changes here in a little bit."

Asked what he's looking for in particular, Rutherford was clear.

"We need to get deeper," Rutherford said. "That's a big goal for us right now. I want more balance throughout the lineup."

Pittsburgh made a move for center Derick Brassard before February's trade deadline to bolster an already lethal attack, but ran into offensive issues once Evgeni Malkin suffered an injury in the postseason.

Rutherford has just under $5 million in cap space to work with this offseason, according to CapFriendly, with Bryan Rust and Jamie Oleksiak among the Penguins' notable restricted free agents in need of new contracts.
