Nope, not buying this gift story one bit! And no, unlike you, I think this trade was a clear loss for Dubas.
Why? Because availability is a very important player asset. He'll likely end up missing more games than he's been available to play. Sure, Murray has good stats with our Leafs, however good stats doesn't define the entire story. We need to see if he'll even be available to play in the playoffs. That will tell us the complete story IMHO.
As a case in point, Dubas had to give up a 1st round pick to get rid of Marleau and the final year of his contract. Murray's contract was for more money and was for a year longer. IMHO a 1st round pick should have been the price Ottawa should have paid. IMHO, it was Ottawa that was given a real gift by Dubas.
Murray better not come up lame again prior to puck drop like he did against Ottawa. He forced Samsonov to play the game he was not expecting to start. Goalies have rituals they go through to prepare to start. Murray had to know sooner than near game time he wasn't comfortable starting. He should have made the decision to pull himself from the game sooner.
Now, having dissed Murray and Dubas, if somehow Murray plays in the playoffs and helps our Leafs win the Stanley Cup, all will be forgiven on my part. Until that happens, I still don't like the Murray acquisition.
