The Habs have accomplished less under Claude Julien than they did with Michel Therrien. It doesn't make Therrien a better coach.How about the results on the ice? He hasn't been bad at all but under his leadership the team hasn't accomplished anything. I also acknowledge that he isn't the GM and can't be held responsible for a badly built team , however it's hard to say if the trade was really a win. We haven't seen many young D flourish under his development (was hoping to see Sergachev being mentored but we know how that ended) and the contract is less likely to get better as he ages.
The only way to argue Subban's been better than Weber is to not directly compare Subban to Weber. Having their teams stand in for the players is a neat bit of misdirection, but it avoids focusing on the two players involved. Objectively, statistically, and yes, intangibly, Weber has been the better player. But, to be fair, Bergevin probably could've gotten a younger core player who could've fit our needs for longer. So yeah, Bergevin didn't max out Subban's trade value.
Which makes it a good trade instead of a great trade.
