It's definitely not worthy of a penalty, it simply should have negated the goal. Incidental contact because Bennet lightly shoved/'crosschecked' Coyle into his goalie, even if it was rather pedestrian in terms of force. Again not rising to level of a penalty but probably should've wiped away the goal
Far softer crosschecks are being called. A near "automatic" penalty this season and last. This crosscheck and one other on Coyle at the end of the 2nd should have been called. Egregious.
Yes, this was clearly interference as well even without the penalty called.
