Quoting: SmartGM
Tyler Seguin when traded to Dallas was that type of deal and Seguin was healty. Tyler Seguin is a 2nd overall pick just like Eichel.
When Seguin was traded from Boston, the Bruins had two top centers in their prime, Bergeron and Krejci and needed wingers, to make a run in the playoffs.
Buffalo is in a total rebuild having already trading Reinhart and Ristolainen while also shopping Eichel.
Several other differences, Boston received two top 6 forwards Eriksson and Smith the only top six in this trade is Gallager.
Second, Jack is significantly better than Tyler.
Third, this trade includes two LHD. Edmundson would be competing with Butcher for a spot, so he is not needed and Harris would be behind Prospects Power, Samuelsson, Bryson and Johnson, so he is not needed.
Fourth Tuch is a LW prospect. he would fall behind prospects Rosen, Poltapov, Peterka, Murray, Weissbach, and Biro.
This is actually an incredibly poor return for Jack and Buffalo is trying to rebuild.
Other than Suzuki and Caufield, Montreal does not have the young talent that Buffalo needs.
IMO once Bergevin got Dvorak, he used the assets that could have been used to get Jack.

You forget one main component of that deal, Peter Chiarelli was the GM of Boston. He is considered by many on this site and in the NHL as one of the worse GM's in this era.
He made many questionable trades with Edmonton, but he did a pretty good job when he was the Bruins GM, until he missed the playoffs his last year.
