The second play in question came at 18:00 of the second period when Mike Smith received a two minute penalty for slashing on Dustin Brown. Brown also received a two minute diving penalty.
Upon watching the replay, you can see that Brown did not dive on the play, as he justly fell to the ice after a violent slash from Smith.
While pokes and slashes from the goaltenders, especially in the playoffs, are not uncommon, Smith takes a clear wind-up to slash the back of Dustin Brown's legs.
It appears that on this play, Mike Smith had intent to injure, and for that, a fine would be a fair punishment. That said, due to the fact that Brown remained in the game and Smith has no history of suspensions, it wouldn't come as a surprise to see no additional discipline past the two minute penalty.
