Berube hasn't been shy of cracking the whip when he feels the team is getting away from their structure.
On Friday, ahead of their game against the New York Rangers, Berube again demonstrated his commitment to high standards, halting practice twice when he observed lapses in judgment during drills.
"We don't want to get complacent, right? That's the biggest thing. Staying sharp," Berube explained. "I stopped it a couple of times. Just execution for me, you know, being sharp and executing.
"It sort of goes back to the last game and 5-0. You take your foot off the gas a little bit. That's where we got to get. We don't want to do that."
