This morning, news broke that veteran Flyers’ defenseman Andreas Lilja would miss 4 months with a hip surgery. Lilja wasn’t expected to be a major part of the Flyers’ defensive corps by any stretch of the imagination, but he will provide veteran depth as someone who can step into the 6th-defenseman role and do a serviceable job. He did play in 46 regular season games for the team last year, tallying 6 assists and no goals, and he was in the lineup for 10 of the Flyers’ 11 playoff games, although he did not record a point. This means that when the Flyers go to training camp, their group of 7 defenseman who will likely be on the roster for the start of the season (with one being scratched every game) is pretty much set: Braydon Coburn, Nicklas Grossmann, Kimmo Timonen, Luke Schenn, Marc-Andre Bourdon, Bruno Gervais, and Erik Gustafsson. That being said, however, the Flyers could also look to acquire another defenseman before the season begins. Notable free-agent targets who are still on the market include Carlo Colaiacovo and Michal Rozsival and blueliners who could be available for a trade are names like Calgary’s Jay Bouwmeester, San Jose’s Dan Boyle, and Phoenix’s Keith Yandle. Restricted free-agents (and therefore, offer sheet candidates) include Montreal’s PK Subban, New York’s Michael Del Zotto, and Washington’s John Carlson.
