I thought this would have been 2-3 games, even though it's the playoffs. This was a pretty bad hit from behind by Hanzal, easily avoidable. Shanahan is too hopped up on whether things cause injury or not. This was an incredibly dangerous hit and
Dustin Brown was very lucky to escape being injured on the play. Even though it's the playoffs, I didn't think the lack of injury would have absolved Hanzal to the point of only getting a single game suspension.
I do, however, agree with this being the only suspension-worthy infraction from the game (Shane Doan was correctly not punished since Lewis was very largely to blame for an incredibly stupid last second turn).
