"I don't foresee anything major happening," Holmgren said. "I'm sure there's going to be some guys available. Whether there's going to be some guys who can improve our team, that is the question."
The Flyers are reportedly shopping defenseman Andrej Meszaros, in an attempt to free up salary cap space to accommodate the acquisition of another blueliner.
Holmgren did not sound overly optimistic that he'd be able to achieve what he is set out to do, but he could simply be playing coy with the media.
"I like the way our defense has played. I know it's not a sexy defense," he said. "Is there a 'Bobby Orr' out there we can get? Probably not. I think our defense has played pretty good overall. Could we improve? I don't know."
According to TSN Hockey Insider Darren Dreger, the Boston Bruins are interested in Meszaros and have held talks with the Flyers.
Meszaros, 28, is in the final year of a six-year, $24 million contract and is scheduled to become an unrestricted free agent July 1.
The Flyers reportedly held trade talks with the Edmonton Oilers prior to the Olympic break, and are believed to be interested in forward Jordan Eberle.
Oilers GM Craig MacTavish prefers not to trade Eberle, but would consider it if the right offer presented itself.
