Thread is hilarious.
The chicken wing was barely an elbow - he was digging for the puck. Even if it was an elbow, he was going about 2mph and didn't even connect. Let's not cry wolf here. Vatrano took offense anyway - fine - and put a lot of weight into a cross check. Fine. Kostin said f*** around and find out, and dropped him with a gloved punch. Might have been embellished, might have been a great punch, might have been unfair to punch but far better to have done it with glove and squared up from the front, not side or back.
Both got offsetting minors. Seems about right given the cross check was also dangerous.
Move on.
