Throughout the entire series, Berube has been preaching discipline and unfortunately, Domi's lack of discipline led to the Leafs falling behind for the second consecutive game.
Despite a lackluster regular season, the 30-year-old has played very well through the first four games of the playoffs, including scoring the overtime winner in Game 2. No one faults Domi for being an emotional player, but sometimes he needs a reminder to play between the whistles and not after them.
