This is a simple one I just posted on hfboards -
Parrish to Calgary for Lydman.
Gotta give to get, and this makes sense from both a personnel (overstock on RW, understock on D), and salary cap (defense more of a premium than forwards) viewpoints. It isn't bad from the Flame's point of view, either.
In my mind, it's better than spending another 3.5 million on a less than first-pairing defenseman if you can get one for 2 million and you can use the remainder to sign a forward that more fits our needs - i.e., a speedy one that plays the left side.
Cheers,
