Seems like a lot of people have given up on Dach. They may be right, but at the same time Kent Hughes said very clearly that the team did their home work on him before making the deal. The spoke to several people and they must have heard things that makes them confidant that they can turn Dach's game around and maximize his potential. Seeing how St-Louis "fixed" Caufleid... it is also easy to understand why habs fan are hopeful that he can do the same with Dach.
This trade goes DIRECTLY into the narrative that Kent Hugues has been pushing since he became the GM, i.e. that the will prefer to add young players that have already been drafted as opposed to pick. According to him, it is easier to project a player that as a bit more experience then a draft pick. I guess that in this case, they have seen enough and learn enough about Dach to know how to work with him, how to use him and set reasonable expectations. Bare in mind, Hughes expectation here may not be yours!!!!
Now, as far as value here goes... Going from Romanov to Dach is pretty good. I LOVED Romanov but lets face it, he's a No4 dman max on a good team and PK specialist. Zero offense in his game, prone to confusion in his own zone. Also, while he hits like a tank.... he's not very strong. I found he got out-work and out-muscled in the corners. So value wise, for MTL this makes lots of sense given the above. The 13th for him is pretty good value.
Now giving the 13thOV for Dach is a question mark and base on what we know now... well I don't think anyone can say if there is a winner as MTL need to "fix" Dach and CHI got magic beans and hope that Nazar will be better then Dach. There are questions mark on both side... Where I think people get side track here is when the compare the return to the Debrincat trade... well that is unfair as OTT got a pretty great deal (despite the player being close to UFA).
