Soucy will be suspended, the question is, for how long.
There's an argument to be made that his intention was to push him and that he was aiming high chest but the hit from Zadorov dropped him lower and it was all timing.
The exchange that I saw was, McDavid was right there, Soucy give him a little push and McDavid responded with a 2 handed slash (which he should probably get a fine for, but won't) then Soucy was just about to crosscheck McDavid in the chest, but the hit from Zadorov altered trajectory of where it landed.
I'm hoping 1 game, I'm expecting NHL will decide to make an example and do like 3 games. They only like to set an example when it's Canucks involved.
There could have been a fine to Kane after game 2 for a dangerous slew foot on Hughes, but nothing.
