Within four hours of NHL free agency opening at noon ET Saturday, Pittsburgh lost third-line center Nick Bonino to the Nashville Predators, left wing Chris Kunitz to the Tampa Bay Lightning, top-four defenseman Trevor Daley to the Detroit Red Wings, and defenseman Ron Hainsey to the Toronto Maple Leafs.

In response, Rutherford signed defenseman Matt Hunwick to a three-year contract with an average annual value of $2.25 million; and goalie Antti Niemi, who will back up Matt Murray, to a one-year, $700,000 contract. Niemi replaces Marc-Andre Fleury, who was selected by the Vegas Golden Knights in the NHL Expansion Draft.
Those moves, though necessary, didn't address Bonino's departure.
"I'm not surprised that we didn't get anything done today," Rutherford said. "We have a long ways to go before we play."
Rutherford said he expects to add a center in a trade before this season begins with another banner-raising on Oct. 4.
"We weren't really looking at one in free agency," Rutherford said. "The prices were a little high on a few guys that we had talked about. … I've talked about enough different things that I'm confident we'll get somebody."
The Penguins don't feel pressured to make a move, though; Rutherford said coach Mike Sullivan has expressed confidence in his lineup, if centers Sidney Crosby and Evgeni Malkin enter the regular season healthy.
"I think it's important now that we don't panic and just go after somebody just to say we got a center," Rutherford said. "I talked to [Mike] about this and he says, 'As long as I got my two big guys healthy.' He says, 'I can work around anything early in the season.'
"We'll move on one when we're comfortable with somebody that we like. It could be in the next day, it could take us a couple months. It could take us until early in the season to make it happen."
With Bonino gone and 40-year-old fourth-line center Matt Cullen an unrestricted free agent and considering retirement, the Penguins could start the season with two sizable holes in the middle of their bottom-six. But Rutherford said he doesn't expect that to be the case.
