Watch the crosschecks, the trips in the corner, and then dumping Paquette in front of the net into a pile of Bruins. Chara knew who it was and what he was doing, which makes it even better. He was in position in front of the net -- it's not like he was hurting the Bruins at all. Had Paquette skated away like he should have, Chara wouldn't have followed. But he kept coming back for more.
After watching Chara for all these years, surely you can see when he gets that "Chara Smash" mode going on? There are times he is out there to stir the pot a bit. He knew he wasn't hurting the team. He also knew there was literally no downside to taking out this little kid. It would only help, and it did. I am sure we will see this Bruins team with it's swag back going forward. Partly from Pastrnak, and Claude's adjustments, and Charlie's comments... but also a lot because their Captain is back.
