I dunno man, I'm clearly a Jets fan but I see a huge difference between them too. With the Petterson hit, you had a player intentionally skate out of his way to attack a guy and throw him down with no intention of a hockey play. With the Oshie hit, Morrissey was at least actually playing the puck when he hit Oshie, then they got tangled and it looked like they fell down together only Morrissey ended up on top. Did he throw him down? Maybe a bit, but I think that's also Morrissey trying to shake Oshie off - he was holding him for sure. Hate the result, but don't see how you can call the two "very similar".
As I said, I can see that they are two different plays.
In the DoPS video on Matheson, the point of emphasis seemed to be the hockey stick between the legs, and the slamming of someone towards the ice.
They are easily tied up going into the corner, the puck then leaves, and the play is done (or should be), Morrissey and Oshie have their arms locked (I'm not going to say who was holding who), but his legs where in a position to throw Oshie off balance. Then Morrissey moves his left hand onto the chest of Oshie and slams him to the ice, and yes, I'm going to say slams, if they just "fell" then Oshies legs don't come up the way they do, Morrissey was exerting force on his chest. At least that's my opinion.
That's why I've decided to compare the two.
