Let me put it this way... You would be screaming for justice if Tom Wilson made that exact same hit on McDavid. In fact, let's exclude Tom Wilson from this conversation completely since you'd obviously like me to.
If Any of the Habs hit an Oiler the same way Connor hit Kotkaniemi, You'd probably be equally furious and want who ever dished the elbow suspended. I get he was frustrated. I love McDavid. I'm one of his biggest fans but that was a dirty play. He hit him up high. If Connor threw a hip check then we wouldn't be having this conversation. I just try really hard to not be bias about these types of situations. Maybe the replay on YouTube I saw made the incident look uglier than it actually was. I'll take correction and admit I'm wrong if that's the case. Regardless, I just value player safety.
