About the only optimism that I can pull from this trade is that, in the last month of the regular season, Oduya and Leddy were a real good pairing for the Hawks. If Oduya's presence helps Leddy grow, that'd be real nice.
But that's probably going to be on the 2nd D-pairing, not the 3rd. And Hjalmarsson makes waaaaay too much money to be a 3rd pairing guy. Ditto with Oduya. One of those two has to have their salary taken off the books, and it won't be the guy that just re-signed.
As some of you said, though, letting Hjalmarsson go could be scary, if he realizes his full potential elsewhere. Glad I'm not making that call.
