When he has something to say about his team, he says, it no questions asked. He will hold the team accountable regardless of what the situation is. For instance, the team lost last night against the New York Rangers by a score of 4-1. After the game, Berube was brutally honest about what the team did wrong, despite running into a hot goalie.
This should get Holmberg to put that extra effort in, moving forward. The team needs all hands on deck, and that means Holmberg and many others have to be better.
