I'm not sure that Lafreniere is showing the progress over those guys. His underlying numbers have trended down and he didn't score at the inflated rates of his first two seasons. If Lafreniere is moved it will be for the same reason Dach and Newhook were moved (stagnation in the system). Newhook like Dach is also a guy who can play center and as we all know that has more value than wingers. The other thing in Dach and Newhook's favour (at least in Montreal's POV, but likely for other teams too), is that they had a lot of control left. Dach and Newhook signed 4 year deals with Montreal and will be RFAs when they expire. Lafreniere has a year less control and is under contract.
From the Habs, something like the Calgary 1st and Sean Farrell seems to fit the general fit of the other two trades, but I'm not super fussed if they try to make a move for him or not. Montreal has enough players to try to develop, they don't need to risk a Drouin-esque distraction.
