Historically Murray has made quick moves after injuries. Maybe we should consider overpaying for Ryan O'Reilly. He can salvage one of the top two center positions and can be converted to wing the following year. While it may suck giving up a good young prospect (anyone but Zibby), atleast we would have someone who can stick with the organization
With the way the 4th line is playing as the team's most consistent/performing line, you have either Latendresse (who needs to play consistently to find his form) or Regin to come out of the line to slot Da Costa in. They may give Regin at least a few more games to get himself into gear as he has also missed significant amount of hockey in the last few years.
