Wow I completely disagree. The Doan hit was from the front?
The approach angle was essentially identical for the Doan hit and the Richards hit on Booth last year. Didn't we all agree that the Richards hit last year was a play that needed to be addressed? The only difference I can discern between the two plays is the extent of injury. Both plays you have a player getting rid of the puck, a defender approaches at the same exact angle and delivers a shoulder to chin shot. On both plays the checker's back skate is even with the puck carriers front skate as the checker thrusts himself into the puck carrier. If anything, on the Richards hit, Richards skates were maybe 6 inches further ahead of Booth than in the Doan hit.
Take away the jersey colors and mirror the images and it would be difficult to tell one hit from the other.
I also completely disagree that a player's rep as a dirty player should have any bearing on the punishment received. Punishment should match the crime, whether it's a weasel like Cooke or Kaleta or Pavel Datsyuk.
Lastly, Hjalmarsson's hit is apples to oranges. The new rule explicitly addresses hits with a principal point of contact to the head, which Hjalmarsson's hit plainly was not. Maybe he should've been punished more severely, but it's a different play.
