* The Colorado Avalanche's star player, Nathan MacKinnon, is playing with a surprising new attitude this season. He's been getting into fights, which is different for him because he's usually known for his amazing skills, not his toughness.
* This change in his play, where he has both points and penalty minutes, is making people wonder why he's acting this way. Some think it might be because he's still a little upset about past playoff games, but it's definitely making him a player to watch for the Avalanche.
