The Flames lost center Olli Jokinen to free agency, as the 33-year-old signed a two-year contract with the Winnipeg Jets.
It appears to Flames are hoping Roman Cervenka can jump into their top-six and man the second line, but the team still lacks a top line center.
Flames GM Jay Feaster has been active on the trade front, actively shopping defenseman Jay Bouwmeester. It's possible the Flames package Bouwmeester with a forward for a top-two center.
Bob Hartley, Calgary's head coach, is starting to map out his game plans for next season and seems prepared with the group he's got, but he understands the roster can still change.
"We will look," he told the Sun. "We're only in July right now and Jay can look at several options."
The Flames added right wing Jiri Hudler, signing him to a four-year, $16 million contract, to round up the team's second line, but if an opportunity pops up to acquire someone capable to centering the first unit, Feaster will jump at the chance.
