I am thinking the same thing.
In fact, I think that is one of the things that is lacking on this team right now; accountability and like-minded folks to keep each one another accountable.
If Lucic plays with snarl 20% of the time, and Stewart plays with snarl 20% of the time, then at least when one of them does something it may wake the other and possibly the team.
You see it time and time again. Boychuk, Ference, or Chara would make a big hit or play with snarl, and it is contagious.
I honestly believe that adding Stewart and Kassian to this team would do WONDERS for it. I don't care if each of them has occasional motivation problems. They will feed off one another.
I think getting their identity back is a HUGE thing. They've lost it since last April. Adding two players, who can play with a nasty edge and chip in is solid. They played Montreal in the first round and tried to play Montreal's game. News flash, that's not smart.
Ference played with an Edge
Boychuk played with an Edge
Thornton played with an Edge
Since they left the Bruins have become softer than I have ever seen them before. Say what you want about skill and speed and how the game is getting smaller and more skilled, but the Bruins play their best hockey when they're getting riled up. Stewart and Kassian can help in that regard... again, if the price is right. Teams used to be scared of the Bruins, why? not because they were small, fast and skilled, but because they were big, tough and mean.
