Hall's arrival has also appeared to provide a boost to Krejci. The veteran pivot was having a solid season prior to the acquisition of Hall on April 12, but since then he has piled up 21 points (6 goals, 15 assists) - including three helpers on Monday night - tied with Marchand for the team lead in that span.
"When I got traded here, I honestly didn't know who I'd play with," said Hall. "There was no conversation about that. But coming here, just kind of the first time we stepped on the ice together, you could see the playmaking ability that he has. And he's done it for so long.
"Just speaking to the people that know hockey, they always told me if Krejci has some linemates he really likes playing with - like he had [Milan] Lucic and [Nathan] Horton back in the day, some other guys have been through - and he's comfortable and he's playing with some players that can play with speed and pace, he's very effective.
"Obviously, he's been much more than that for me. I've never played with right-handed centermen at all really in my career, maybe a little bit with Sam [Gagner] in Edmonton, but to have a guy that doesn't have to go to his backhand to pass me the puck when I'm coming up the wall, I think it adds another dimension to our attack off the rush.
"Smitty as well. I think Smitty and I play pretty similar styles. We like to create offense in any way, doesn't have to be off the rush, can be off the forecheck or in the zone, creating turnovers. Being hard to play against is something we take pride in and I feel like we've done that."
That havoc was on full display on Monday night as Hall engaged physically with the Islanders on multiple occasions - he took a cross-checking penalty on Leddy in the second period - and also drew two penalties. On the second penalty, Hall took advantage with a sharp-angle, power-play blast from the left corner off a cross-crease feed from Krejci to give Boston a 1-0 lead with just 39 seconds left in the first period.
Bruins coach Bruce Cassidy also made sure to point out Hall's defensive game as part of the winger's standout all-around effort.
"I thought he was really good tonight," said Cassidy. "If you think back to the end of the first period, we had a real good first period and we were on a power play and Charlie [McAvoy] got himself in a tough spot on the boards on his offside. Those are tough pucks. And they were able to make a play on it and he backchecked from goal line to goal line. Tried to keep it out of our net.
"He's a real invested player for us at both ends. He drew a penalty. He's finishing plays now. I think he's opened up a little more…just personality wise. So that tells me right away he's more comfortable in the room and it shows on the ice, obviously.
"He's been good since he got here - from Day 1. Really showed tonight. He finished some nice plays, and we need it. That's the Taylor Hall we were hoping to get, and so far, so good. Now playoffs are a different animal. Hopefully he's excited to get back in the playoffs and get going. We'll see where it leads."
