A minor penalty for a play like this seems to be a bit lacking. Plays like these are genuinely among the most dangerous in hockey as Raymond was completely unaware of what was about to happen. As a result, he did not have adequate time to protect himself as he fell to the ice. Luckily, Raymond appeared to be okay, but the Department of Player Safety should be taking a look at this one as a potential suspension for Gudas.
Regardless, the NHL needs to get plays like these out of the game. This play serves no purpose other than to injure players, especially as it was away from the play. The league needs to set a precedent with these kinds of plays, something they have failed to do in the past.
