Im not sure if it is blind optimism.
Before the deadline, I firmly believed no team would be willing to give up a 1st or 2nd for Drouin, Armia, Dadonov, Hoffman. In fact, I don't think Drouin, Hoffman and Armia were tradeable. I just can't see teams being interested in those players.
Monahan and Edmundson were the two players I expected to get something for, but they are hurt.
Then there is Dvorak, Anderson, Savard who I think have value, but have tricky contracts. Would teams be interested in giving up a 1st or 2nd or prospect for these players? Maybe, but I suspect some money would have to be eaten.
I just dont think we had desirable assets that were available. The two players that had deadline value were hurt.
I think we see Dvorak and Anderson moved at the draft where teams are more likely to pay up for term.
I'm not making excuses, I just don't think we had the assets available for what teams are looking for at this time of year.
