I don't agree with this he should of been suspended, but I don't believe Matheson should of been suspended 2 games for his throw down of Pettersson, I'll explain why.
Hockey is a physical sport, throw downs happen it's hockey, someone trying to over strengthen someone else that's just part of the game and being competitive, you can't eliminate everything. Players also wear certain protection to protect them, so when certain plays like that happen they can still be protected, but when a player doesn't have that certain piece of protection on and his then put into a position to get seriously hurt due to it then I have a problem with it especially when you can see that, a red flag should be going off like hitting someone from behind. Let's face it if Panarin head smashes that ice first that could of been something very ugly to see, but if he had his helmet on still then was thrown down he has the protection from cracking his skull open. This is why I never agreed with the Matheson suspension, Pettersson was still protected, it was definitely a roughing penalty but shouldn't of been a suspension, where Wilson should of been a suspension, because the outcome could of been a lot worse tbh with a player with no helmet on.
NHL just so consistent
