When I think of Berube, I think of his composure and stalwart attitude during the Stanley Cup run.
The Sharks OT winner off the hand-pass is the shining example of this. When the refs were grouped together and skating towards the exit at the edge of the rink, the Blues players were pleading their case and angry that the obvious call was missed. I recall Schenn slamming his stick on the glass and yelling, along with several other players totally upset.
When talking to the press after the game, Berube had none of it. He didn't complain once. When asked about it, repeatedly, he kept saying "we're moving on. There's nothing to talk about."
It was honestly a little wild at the time.
Compare his reaction to the reaction of each opposing coach in the four rounds. Every single coach of the opposing team had one or more games where they vocally complained about reffing and the Blues physicality. Maurice in particular really surprised me. He seemed defeated after each of their losses, totally exasperated and at wits end.
Meanwhile, Berube, when faced with what could have been the most significant and obvious missed call in the history of the franchise, kept his goddamn cool.
It impressed me then and it still impresses me now.
