Understandable, I can see why no one would like to have Alzner in their organisation.
As for Dahlen, he's currently dominating in Sweden. Imo he's playing in a way too weak league. He could have a future in NHL.
As for True, I think he's a bit weaker equivalent to that of Jeremy Bracco, but with being able to play C he gains some value. They both are 22 and haven't made their debut yet, but they both have potential. Think when it comes to what they get, DET could be a total winner here when compared to what they're actually losing, namely a bottom-4 D-man. Nothing else.
While Nemeth has been good defensively he is very responsible and better than I thought he would be. Yzerman brought him in to help with the transition Green, Daley and Ericsson this is their last season in Detroit, and that leaves DeKeyser as the only dman with any real experience. For Hronek, Cholowski and Bowey this will be their first full NHL season. I agree with you I think Nemeth is about a #4 or #5. Since he was brought in for a purpose I don't think he gets traded but he isn't the reason I don't think this trade happens.
The main reason is Alzner and his contract he is buried now and Montreal buried him twice last year he no longer good enough to play in the NHL. With Detroit having 11 players signed for next season and they have Mantha, Bertuzzi, and AA to resign they are the most important and the most expensive players for Detroit to resign. The Detroit also has DLR, Ehn, Erne, Perlini, Hirose, Hicketts, Sevechnikov, Kaski, Kuffner Saarijarvi and Turgeon to resign. They have about $35.5M to do that with and I know they won't resign them all but it would be nice to have some cap to maybe sign a free agent. Plus Detroit is sill rebuilding and aren't going to trade 3rd round pick in very deep draft.
I really don't think Dahlen comes back the league he is in now the Allsvenskan (Sweden version of the AHL and he is there because his SHL team sent him there for whatever reason. True is young and could be a good NHL player but most NHLer's see NHL action at 20 and every year after that the likely hood of making it to the NHL goes down. Exceptions college players and some players playing in other countries, but this this is True's 3rd pro season.
