Also: circumstances have changed for Tom. He's quickly realised he's not going to step right into the top 6 D of whatever NHL organisation he wants. He thought he was a blue-chip prospect (so did we, to be fair) but now it should be clear to him (one would hope) that he needs to earn his place in the NHL.
I don't see the history between the Flames and Erixon being an issue with anyone other than some fans.
You have to think that the Coilers will put in a claim though. Sorry Tom!
