Emotions run high through every game in the NHL. It is part of the game and something that can be used in a team's favor or against an opponent, for better or worse.
However, a big part of how emotions function game-to-game is how a single player can evoke dread in foes just by taking the ice.
Every team has a player (or two or three) that opposing teams don't like facing. Whether it's because of how dominating their presence is, how nasty they play or how relentless they are, they're the type of player guys hate to play against.
