And it wasn't just the scoring that highlighted the Bruins' convincing effort. Boston also upped its physical intensity, especially after a dangerous hit on Charlie McAvoy in the third period that left the blue liner - playing in just his second game back after a 20-game absence with a concussion - on his knees behind the Bruins' net.
Roughly a second after McAvoy got rid of the puck, Toronto forward Zach Hyman delivered a crushing blow, which prompted Matt Grzelcyk (assist) to drop the gloves with Hyman in the neutral zone. Grzelcyk received 30 minutes in penalties on the play (five for fighting, five for cross-checking, and two 10-minute game misconducts, one for not having his jersey properly secured).
"They're real good buddies," Cassidy said of Grzelcyk and McAvoy, the former Boston University teammates. "And it just seems like every time one of those hits happen it's our smallest guy that's the closest guy in the vicinity, but they always go and show up, so you have to give them credit for that."
McAvoy was ushered to the dressing room as part of the NHL's concussion protocol, but returned to the bench with just over two minutes to play, though he did not take another shift.
"That was the league-mandated protocol. He went and got through it," said Cassidy. "I suppose until tomorrow comes and he wakes up, we're all going to be a little bit on pins and needles, but he was cleared to come back…hopefully he wakes up feeling great and knows, 'Well, hey, I'm kind of back to myself.' That would be best case scenario for us."
