With Roman Cervenka reportedly heading back to the KHL for the 2013-14 campaign, the experiment is over.
The Calgary Flames took a chance on Cervenka after he dominated in the KHL, but he was never able to adjust to playing in North America. That being said, his tenure with the Flames wasn't disastrous. In fact, with nine goals and 17 points in 39 games, he probably would have gotten another shot with the Flames or a different NHL team if that's what he wanted. At the same time, he highlights the risk associated with grabbing mid-20s European star that has no prior North American experience. Sometimes it works out, but drafting a player in a fantasy league with those credentials is a roll of the dice.

Roman Cervenka has reportedly signed a three-year deal to return to the KHL with SKA St. Petersburg.
He had trouble adapting to the North American game with the Calgary Flames during the lockout-shortened season. He recorded only nine goals and eight assists in 39 matches.

Leland Irving's time with the Calgary Flames is likely done.
Irving is scheduled to be an unrestricted free agent, and the Flames have given little indication that they feel he's part of their future plans. He had a 3.33 GAA and .883 save percentage in six games this season. Irving's agent Ritch Winter naturally sang his client's praises, both saying that Irving will become a solid number one goaltender in the NHL and would like to re-sign with Calgary. Perhaps Irving will eventually become a good number one goaltender, but we don't have high short-term expectations for him. However, that could change if he signs with a team that lacks major competition.
